Part number help

[Jeffrey S.]

Hello all. I have two parts I need help in finding the application. First, rear shocks #3192341 dated 345 of 70 and 12 of 71 which puts them right for an early to mid '71 Corvette. The broadcast code labels are "HL". They are "Pliacell" and are identical to the ones on my '69. The second is a tach drive distributor with a band part number 1111263, 4 D 10. The cap is a "Patent Pending R" (this may or may not be the original cap). As always any help is greatly appreciated.

Not sure about the shocks, but the distributor is the over the counter TI unit that was available for years with a '74, '84, 'or '94 year of production

Yup, Dickie is right on, as usual. By the way, I don't think there are many parts in that distributor that are the same as, or interchangeable with, a standard tach drive distributor. Even the housing, shaft and bottom gear are different. Believe the stationary pole piece is unique also.
The tach driven gear is the same though.

I can't find any record of those shock part numbers having been used for 1971 Corvettes and "HL" is not a broadcast code that I can find used for 1971. It's, of course, possible that they were but I can't find any record of it.

Joe, Michael, Dick:
Thanks for your responses. Is it possible that these shocks were used on another GM car (Camaro perhaps)? Also, Michael, you said that very few parts are interchangeable with stock Corvette distributors including the bottom gear. Does this mean that it would not even fit a stock engine?
Thanks for the help.

Jeff, it's been many years since I've worked on one of these 263 distributors but if I remember correctly, the main shaft is larger in diameter than a standard distributor. It also rides in ball bearings instead of bushings like a std distributor, so I think the housing is unique.
The rotating pole piece would also have to have a larger hole to be able to fit over the large main shaft.
The same would be the case for the gear at the bottom. Also, the bottom gear teeth were cut in the opposite direction so the unit could be used with the L88 reverse rotation gear drive cam.

I seem to remember that the only pieces that were the same as a regular Corvette distributor were the tach drive gear and brass bushing for it. Possible that the stationary pole piece is the same but I'm not sure.

I think that a conventional rotation bottom gear can be used, somehow, which would make the unit at least function in a normal Corvette engine but I don't think the 263 had provisions for a vacuum advance unit.

This was a "service only" heavy duty part that was never used in production for any car.

I'd say that it's a virtual certainty that these shocks were used on some other GM car (even though Delco did manufacture SERVICE shocks for non-GM vehicles they would not have included broadcast code labels). However, the GM car was not necessarily a Chevrolet. It could have been a Chevrolet, but I can't confirm that. Keep in mind that the part number on these shocks is a Delco Products part number and NOT a Chevrolet part number. So, that means these shocks could have been originally used on ANY GM vehicle. There were many that used shocks configured similarly to Corvette.

As far as the distributor goes, it's just like Michael has advised. The GM #1111263 distributor was a SERVICE-only, ball bearing-type, tach drive distributor with transistor ignition. No parts except weights, springs, rotor, cap, tach cross gear, and fitting are interchangeable with other Corvette distributors. As-is, the distributor cannot be used on a Corvette engine because of the reverse-rotation gear, designed for use with gear drive cams. However, the gear can be changed to a standard rotation and then the distributor used on a Chevrolet engine. You just never want to need internal parts for it other than those described above.

As Michael advises, there is no vacuum advance installed on this distributor and none can be installed due to the special housing used which lacks any provisions, at all, for vacuum advance.
