Restoration / water pump question
« on: March 27, 2024, 08:33:02 PM »
The water pump on my 69 Z28 just started to leak at the shaft seal (photo attached).  I have owned the car since 1982 and never replaced it.  I have reviewed most of the messages from team members, but still looking for advice on 2 questions:
1. What is a J48 code? Most of the others I see have 3 numbers after the letter.   
2. If original, should I rebuild it and what's the best way get that done?

Thank you for all the great info on this site.

General Discussion / Radio recommendation?
« on: December 07, 2023, 05:17:38 PM »
My 69 Z28 doesn't have a radio and hasn't since I got it in 1982.  It was gone when I bought the car.  I am looking for any advice or recommendation of one to buy.  I want it to look as original as possible, but would really like to have bluetooth.  Custom Autosound offers the 740, does anyone have any experience with that one or can suggest another?

Originality / oil fill tube on intake manifold-is it original?
« on: October 04, 2023, 10:08:05 PM »
Attached is a photo of the intake on my 1969 Z28.  Question:  Is the oil fill tube original?  The block is not original, but the 1974-1978 owner told me he had the engine rebuilt using all original parts except the block.  Intake part number is 3932472.

Restoration / windlace molding for 1969 Camaro
« on: September 10, 2023, 11:51:10 PM »
I am replacing the windlace moldings on my 1969 Camaro, and there is a size difference between the old ones and the new ones I received with my master interior kit.  I'm looking for some advice on what came originally on the car.  Photo attached showing the old smaller, more narrow molding and the new ones.  The new ones being larger now create interference when the door closes where the old ones did not.  What I don't know is are the old ones original, or are the new ones the correct size for original?  I did review past messages but did not see a similar question.  Any advice would be appreciated.

Restoration / installing dash pad metal clips on 69 Z28
« on: August 25, 2023, 02:50:08 AM »
I am replacing the dash pad on my 69 Z28.  Looking for the best way to hold the 6 metal clips in place on the new pad.  I have installed them before on another pad many years ago, without any adhesive, but some don't hold well and seem to rattle later.  I have heard of epoxy, super glue, etc., just looking for your thoughts on the best method to hold clips to pad.

Restoration / shifter bushings for 1969 Z28?
« on: July 17, 2023, 02:43:03 PM »
I just cleaned up the original Hurst Comp Plus shifter on my 69 Z28 and it had some rubber or plastic bushings (mine were crumbling or missing) in the joint where the shift rods attach to the shifter body.  Are those available and/or needed?  I had purchased a Hurst Pit Pack but those did not work.  For now, I reassembled it with some lube and without the rubber pieces.

Restoration / window regulator roller repair?
« on: March 15, 2023, 07:07:34 PM »
My 1969 Camaro needs the rollers replaced on one of the window regulators (photo attached).  I was able to find a 3 piece set, and they will arrive in a few days.  They look to be a pressed pin with the end mashed to secure it in the regulator.  Any tips from the team the best way of replacing them?

Restoration / Rust Remover
« on: January 10, 2023, 12:23:48 AM »
I want to remove rust from the trunk floor of my 1969 Z28.  It is pitted as well as has some small holes.  I have seen info on Evaporust from this team with good reviews and have a friend who uses POR15.  I have never used either of them.  Can anyone from the team advise on a preferred brand?  I see Evaporust also comes in a gel, would that work better?  Any advice would be appreciated.

Restoration / 1969 standard interior seat foam question
« on: December 07, 2022, 02:41:47 AM »
I have a 1969 Z28 with standard interior, am restoring it to original ivory color.  The upholstery shop called today and told me I need seat back foam with wire in it vs. the original seat foam (without wire) I provided.  The seat bottom springs were replaced and the standard foam worked fine.     See photo attached, original seat back foam is on right.     I can find seat foam for sale with and without wire, the only 2 options I can find.  Did the seat bottom come with springs attached to the frame, and the seat back come with springs (or wire?) in the foam not attached to the frame?  Just trying to clear this up before I order more product.  No one has them in stock and it looks like I have to wait several weeks or months to get them, just wanted to make sure what I order is correct.  Thank you.

General Discussion / member locations and recommended installers
« on: November 04, 2022, 02:15:43 PM »
Is there a way to find other team members in my area I could connect with?  I live in Jacksonville, FL, and it would be great to know if there are any others in my area where we could share car info, local show info, recommended installers, etc.  I searched Florida in the member list and only 2 came up without locations.

Originality / hood/headliner insulation question-1969 Z28
« on: October 12, 2022, 09:18:46 PM »
Did a 1969 Z28 come with hood insulation if it didn't have the cowl induction setup?  My Z28 has the hood scoop w/302 emblems but no cowl induction air cleaner.   

Did the car come with insulation above the headliner? 

I am starting to restore it for the 2nd time (I've had it for 40 years) and want to get it right.

Maintenance / 12 bolt posi oil / Muncie 4 spd oil recommendations
« on: October 07, 2022, 11:34:19 PM »
Does the team have a recommendation for gear oil for a 12 bolt posi ('69 Z28) and for a Muncie 4 spd?  I have read several posts about using GL4 instead of GL5 for the Muncie due to synchro wear, is that accurate?  Is there a recommended brand or two? 

For the diff, does it need to be GL4 or 5, does it matter? In most stores, all you find is GL5.  I will add the GM limited slip additive to whatever oil I get.  Thanks.

Decoding/Numbers / Muncie transmission ID-1969 Z28
« on: October 04, 2022, 10:58:12 PM »
Attached are 2 photos of the 4 speed trans in my '69 Z28.  It is a Muncie 4 speed, case is 3925661.  The stamped codes look like CC1(a closer look may be CG1 or C61?), then 35585, but I can't correlate those into a final ID from the decode chart I received from the team.  Any help for a final ID would be appreciated.  Thank you.

Decoding/Numbers / Where to find date codes, etc. on 12 bolt diff - 1969 Z28
« on: September 30, 2022, 07:15:59 PM »
Where I can find the date codes and any other stampings on the 12 bolt differential on my 1969 Z28?  The diff has been undercoated and painted several times before I got it, and I want to know where to clean to find the numbers.  Attached is a photo showing some numbers I found on the right rear next to the diff cover.  Thanks for any help.

Originality / 1969 tail light bulbs
« on: July 18, 2022, 11:56:47 PM »
I have a 1969 Z28 (non-RS) and have a question on the correct tail light bulbs.  When my parking lights are on, the inboard parking light is much brighter than the outboard.  Current outboard parking/turn signal/brake light bulb is 1157, reverse light bulb is 1156 and inboard parking light bulb is 1156.  Is that correct?
