I'll check the axle that I got that I think is shorter. Are there some numbers or something that I can look for that would identify the axle? I am pretty sure when I bought the axle it was advertised as a full-size 65 axle. If it is the same length I am going to have to re-think my wheels...
If nothing else I am having a blast with the old pontiac... it's been in my family 41 years... thanks for the info and I will post what I find. I will also look for the article I found, probably confused what I read... wouldn't be the first time with pontiac stuff.
