Are they spotweld indentations the full width of the panel, or larger "dents"? Got a photo?

"Dave's Small-Body HEI" can convert your existing "small" distributor to HEI if that's what you really want.  Smiley

Based on your symptom, I'd vote for the input shaft bearing. With the clutch pedal on the floor (clutch disengaged), the input shaft isn't turning - the only relative motion is between the input shaft and the pilot bushing, and the throwout bearing is rotating. When the clutch pedal comes up and the clutch starts to engage, the input shaft spins up, and when the pedal is all the way up, motion stops between the pilot bushing and the input shaft, and the throwout bearing is off the clutch fingers and stops rotating.

What's the data for the car to match it against? VIN, cowl tag, model year, trans, axle, VIN derivative stamped on the engine, etc. ?
3681  Camaro Research Group Discussion / Decoding/Numbers / Re: Not Camaro but weird build sheet on: October 13, 2006, 09:24:14 AM
Yup, Doraville ran out of pre-printed forms and used forms from Kansas City until theirs showed up from the printer - I posted over there.
3682  Camaro Research Group Discussion / Restoration / Re: Parking lights on: October 12, 2006, 10:12:14 AM
Nothing is wrong - parking lights "on" with the headlights didn't start until the 1968 model year; some guys with 67's later jumpered the terminals on the headlight switch so the parking lights would be "on" with the headlights.

Here's the rear end of an original passenger side outer fuzzy - it's tapered somewhat to round it off, appears to have been done with an abrasive.
3684  Camaro Research Group Discussion / Decoding/Numbers / Re: TRANSMISSION CODDING HELP on: October 11, 2006, 11:20:13 AM
T is Toledo plant, 7 is the model year, E is May, 05 is the 5th, D is day shift.
3685  Camaro Research Group Discussion / General Discussion / Re: 1967 aircond on: October 11, 2006, 11:14:50 AM
Yes - Harrison evaporator box ("suitcase"), and Frigidaire compressor.
3686  Camaro Research Group Discussion / Maintenance / Re: Fuel Lead Additive on: October 10, 2006, 11:59:01 AM
If you have heads with 2.02/1.60 valves, machining for exhaust valve seat inserts can be very risky unless it's done by a shop that REALLY knows what they're doing; 2.02/1.60 heads are prone to cracking in the very narrow region between the valves as it is, and the chamber roof isn't very thick in that area - an inexperienced machinist can easily go through into the water jacket when cutting the recess for the seat insert.
3687  Camaro Research Group Discussion / Maintenance / Re: M20 clutch adjustment on: October 10, 2006, 11:53:05 AM
Nope - as the clutch wears (disc thickness is reduced), the effective length of the lower rod will be reduced - it will get shorter, not longer. As the disc wears, the outer end of the clutch fork moves forward as the ends of the diaphragm fingers move rearward.
3688  Camaro Research Group Discussion / Maintenance / Re: Fuel Lead Additive on: October 09, 2006, 10:06:54 AM
"Lead additives" don't contain lead - it's illegal to sell tetraethyl lead, as it's a strong carcinogen, easily absorbed through the skin. You don't need any "lead additive" - exhaust valve seat recession isn't an issue unless the engine is in a boat or you pull a trailer at 100 mph all day long; all lead additives will do is 1) Lighten your wallet, and 2) Eat the protective plating off the inside of your float bowls (the "additives" are LOADED with alcohol, except Jack Podell's, which is 99.8% kerosene).  Shocked

John, do you have any idea why the ones with the mold cavity numbers don't have a part number too?


Nope - generally it was optional on the drawing for the part number to appear on the part, unless Engineering had a reason for it to be required.
3690  Camaro Research Group Discussion / Originality / Re: Where are the part #'s ??? on: October 08, 2006, 08:34:08 AM
A good friend of mine retired seven years ago from GM Legal (spent the previous 30 years with Chevrolet Engineering) and was an occasional source for rare Chevrolet drawing, ECR, and Work Order information post-retirement, but since then the "moles" he had at Legal and in the archives have also retired; between that and multiple GM internal reorganizations, those contacts have been lost.
