3.38 ratio diff

[DaveyB]

Thanks again for the info, someone has offered me a 1.6 pinto and so thought I would be going down this route using that engine, I have some drive shafts and no diff, have just been looking at diffs for push in shafts and been concerned that they may not fit I know of a 3.62 diff that will fit and I have seen a 3.92 but I,m not sure if that will fit, and not sure of which one to go for any suggestions. Hope I making some sense!
