Is there a parts book that lists interchangeable parts between the GM A body cars?

 

Hollander's still in business. Google "Hollander Interchange."

 

Hollanders is unfortunately not a comprehensive document. For example, Hollanders shows that only Cutlass disc brake spindles can be used on a Cutlass. Keep in mind that the Hollander interchange database was developed by reports from wrecking yard operators, so it's about as accurate as the Olds FAQ. Fortunately, Hollanders is conservative if anything - it usually won't give you wrong info but it won't necessarily give you ALL the interchanges possible.

 

So what do you use, Joe? Aside from your vast experience, I mean.

 

I had a Hollanders but experience and other sources augment that. For example, we know that all 1964-72 front spindles interchange, though early ones have smaller bolts that hold the steering arm in place. Hollanders does not point this out.

 

I think Joe uses a Cray computer running ACES, PIES & myFITMENT
