49’ Series 88 - Throttle Pedal Direction

Trying to replace the accelerator pedal on my 49’ 88. The original pedal appears to be mounted with a hinge with a brass pin? This hinge assembly is bolted to the floor with 2 7/16” bolts. There isn’t a rod attached to the back of the pedal. The replacement pedal from Fusicks looks like it pops onto ball headed bolts but the original pedal just appears to be a hinge/pin design. Any help would be appreciated!

I'm surprised you were able to find parts for your Oldsmobile. Even from Fusick.

What kind of linkage is currently on your carburetor? I actually had to get aftermarket carburetor linkage for my 71 98 when I installed a Summit carburetor on it. Kits from aftermarket suppliers like Lokar should have directions that are easy to follow.

49’ Olds Throttle Pedal

It’s the original Carter WGD carb with mechanical linkage. Looking like I’ll just have to remove the old rubber from the existing pedal and clad it with a new piece. Can’t find any of the bracket - pivot style pedals out there that wouldn’t require a lot to make work.

Evidently, there were two different designs of accelerator pedal used on 1949 Olds.
According to the parts book the 1949 second design was a stud mounted pedal.
Evidently, you have an early '49, and that's why the Fusick supplied pedal wouldn't work.
See group 3.451 on the page below.

Good find Charlie. Looks like Chevy/GM used a similar design on trucks in the 50’s as well. With a search of that part# 3701621, it’s slightly different than the version in my car. The hinge location is higher and the pedal is much wider. The existing pedal actually looks very similar to the Fusick’s offering but the back is different. Thanks for the info!

Thanks Bob, I removed the pedal, cleaned off the old rubber, tapped an aluminum pedal and bolted it to the existing. Couldn’t find an original to replace it with and having the original revulcanized seemed too complicated. Although it’s not original, I’m happy with the outcome. Here’s a pic of the original for future reference…

For future reference, here’s what the early 49’ pedal looks like.
