Restoration / Re: undercoating
« on: October 21, 2018, 01:37:18 PM »
The factory specified undercoating be applied as shown in the Assembly Instruction Manual.  UPC 11/13 Sheet B1 shows where it was applied inside the front fenders.  Basically only the inner rear part of the inner fender was coated at the factory.  If you have more than that on your inner front fenders, it was not factory applied.  Rear inner wheel wells were coated as well but it may have been part of Fisher Body plant procedures. You can compare front to back.

I actually have used a "Stinger" magnetic trigger conversion for a bit and now use the GM points (acting as a trigger switch only) with a Crane Multispark CD setup and stock coil.  The points electrical contact surfaces do not wear out because they only carry a small switch current this way.  I get an adjustable rev limiter with the Crane box so that is a plus. Box is mounted inside car under the center speaker grille.  Can set RPM limit to 2500 for "Valet Mode".  Pretty handy.

That flywheel is for the 11" clutch.  You may be able to resurface it and run it if not heat cracked too bad.

If the disk has enough material on it, and it is not warped, and the springs are still tight, you could TRY to use it.

The pressure plate can get heat damage and it will be difficult to diagnose visually.  If the heat checks are not too bad, you can bench assemble the clutch to the flywheel and see if the diaphragm fingers are all still aligned with everything torqued down.

All that but still comes down to whether or not it will do its job.  If you adjust it properly AND it still will not release, you will need to pull the whole thing apart again to replace it.  If the pressure plate springs are heated to where they will not clamp hard enough anymore, you will need to pull it apart again and replace the assembly.

Replace the throw out bearing for sure and examine the pilot bushing to see if you can reuse it.

OR....just replace it now.

I have removed and replaced my clutch 3 times in one day to fix a damaged pressure plate that "looked" good.

It was a cheap flat to semi gloss which the castings were dunked in prior to machining.

Nice job on the M/C.  Makes me want to refinish mine now.

LOTS of odd cars and combinations out there.

Mine is 10A with no console, no tach or guages or spoilers but it did get (ugly) light green custom interior and optional radio with kick panel speakers.

Too early for "Tach required".

With any car, if you are serious, do a personal on site inspection BEFORE purchase.  I don't care who the seller is.  That way you reduce the chance of any regrets.

Arms length only transaction is my advice here.  Ronald Reagan said it best....."Trust, but verify".

I would bet the boneyard has a LOT of those.  Not sure if they are fully generic or not but I would try looking for a period correct GM product to scavenge one off.

Might be Jeff Byttner's car.  He had one like that back in the day.

VIN in ad is wrong.  Not even a '69.

My 2 cents - Water pumps do one of three things - They either leak coolant out the weeping hole, or the bearings fail causing them to fall completely apart, or they pump water.   Thats all.

Grab the upper and lower radiator hoses to see if you have any flow.  Bottom hose temp should be close to top hose temp if you have water flow. No flow makes the thermostat suspect.

If you overheat while driving at highway speed, the fan is not a factor.  Fan is important when driving at slower speeds or stop/go traffic.  Check for missing blades.  if fan is new to you, check for proper rotation direction - Not all fans rotate the same direction.

Fan clutch is not that expensive and easy to change out if it is dead.

Thermostat is easy to check with pan of hot water to see if it opens.

 My bet - The floors are WAY too far gone.  We will never see that sad shell on the road again.

Seems possible that the gang stamp holder still had all the numbers in it from the previous car and it was re-used in error.  The error was likely discovered and then corrected.  I would believe it.

Sounds like a cool project.

I think the big block base was same as small block base but the spacer ring was used to make up the difference in height.
