Late 68 wiper door actuator

[Mike E.]

I'm helping a friend with his late 68 (trim tag August 8). I looked through my fourth edition 68-69 JG and didn't find my answer, but could just have missed it. which style wiper door actuator should this have--the cylindrical one or the double pie pan type?

Re: Late 68 wiper door actuator

My 1968 was built in FEB 1968 and had the cylindrical one until the shaft broke in 1974. GM parts had only the pie pan type to replace it.

My July 18 built 68 had the cylindrical one which I believe was original when the shaft broke a few years ago. I found a correct replacement through a question on this site. I still have the old one and the box the new one came in. I'll post more info from the box later if it's useful.

Rich when my 68's shaft broke and after I installed the replacement the pan type I threw the original away. Later after becoming a NCRS member and learning that original parts are valuable, I wish that I had kept it. If my original was still on my 68 today and the shaft broke today I would attempt to repair it.

Mike, the double pie pan version didn't start until late in the 1969 model year. All 1968's had the cylindrical version.

The new one from GM Restoration parts has the box marked 653153 WPR DR ACTUATOR YR:69E

I saved my old one with the intention of getting it repaired some day. You know how that goes. I think the difference between the original and The "69E" version is the shaft has a larger diameter on the new one but I can't remember now.

Yes, 1968 used a shaft with a 1/4"-20 thread, and early 1969 production used a shaft with 5/16"-18 thread.

Re: Late 68 wiper door actuator

There is a slight difference in the canister where the lid crimps on. I have a repo on my April 68 car but saved the original. There's an ad in the Driveline from a P. Demmel of Plano Texas who restores them for $150.00 and takes 3 to 4 weeks. Haven't sent mine out yet. Has anyone used this service? Results ? Rich

Any possibility of late 68 having the 5/16 shaft? My June car has one. I have always assumed it to be wrong

Re: Late 68 wiper door actuator

I believe mid to late 68 s used the 5/16 shaft, not sure where the mid point is by serial number but I think a June car fits. My April car is a three owner with 37,000 original miles and it has the 1/4" shaft so I must be close to the end of the early cars. First model year cars are fun. Rich
