Anyone have a source for the plastic bushings that fit on the post that the weights are on. Dist # 1103274 Maybe 1976 year? I would like to keep the stock weights.
Thanks

Standard ignition part# DG54. I have also bought them at NAPA under the ECHLIN brand of ignition parts.

This has been awhile back so, they may not still be available.

Bushings also come in the aftermarket advance curve kits...

Thanks Jake

Bill, I tried the MR Gasket Kit and it is junk, you have to use the recurve kit and the bushings don`t even fit their weights

Figures.

Is this for an older HEI or a computer control one?
Evidently, according to MSD, the computer HEI uses a different kit...

Older GM HEI. Correct, the newer HEI do not use the weights. The Summit one looks similar to the Mr. Gasket, the bushing colors are different. I want to keep the stock weights.

Some more info, apparently the DG54 has indeed been discontinued by Standard. I scored 1 set off ebay and it has been shipped. I have not gotten by NAPA yet to try them for a spare set.

just for the sake of clarification for people in the future: some trucks in the early 80's had computer controlled distributors that had mechanical and vacuum advance... it was a strange time..

Four-pin module: Stand-alone ignition. Mechanical centrifugal and vacuum advance.
Five-pin module: Takes input from external source to retard timing electronically. Mechanical centrifugal and vacuum advance. At least two different five-pin modules--and at least three different outboard trigger mechanisms, but all are used for electronic spark retard.
Seven- or Eight-pin module: Full computer control of spark advance. No centrifugal or vacuum advance.

Schurkey, Thanks for posting the distributor info. From what I can tell the plastic bushings are no longer available. The NAPA DP 112 has been discontinued as has DG54. I have found a replacement I hope. I will order them Monday and see if they will work.
