How do I determine which cover I need for a Cutlas 350 w/auto tranny. It was installed in my 57' Olds 88.

I'm looking a Summit;

You need the dust cover for your trans for an Olds motor. The Summit "universal" cover has no starter notch, so you can cut the one you need. Chevy/Buick motors use a passenger side starter. Olds and Pontiac use a driver's side starter.

 

Thanks Joe, it came with a cover in the trunk, but not the right one!!!

 

How about an nice NOS or used GM part?
Proper fit and appearance

 

Thanks, I'll keep you in mind, I got a bone yard near me that I need to check first!!
