    will an adapter be needed to put in a 205 in place of a 208 in an 83 with 465 ? anything else ? if this 83 465 tranny has 32 spline then will a th400 205 case work on the 465 ?

    searching forum right now

    thanks

    What did the 205 come out of? Does it use a figure 8 or round bolt pattern adapter? I'm pretty sure that the 465 will have a long 32 spline tailshaft (since it was originally mated to a 208).

    **Assuming it's a figure 8 style 205** I think you can put the 205 on the 465 using a 4 spd adapter and a short 32 spline female input shaft (like a TH400 application). Never actually tried it but I measured the parts one time and it would be VERY close to working.

    The figure 8 is pre-85 and the round adapter is 85 on.

    I guess the easiest way to tell the difference in the truck would be the t-case crossmember. The figure 8 adapter is tall so the crossmember is flat all the way across. The round adapter is shorter so it uses the " W " shaped crossmember.

    If you need pics I have both style adapters and crossmembers at home.

    If you talking about what 205 the easiest to put in it would be a pre-85 TH400 case but those aren't exactly lying around. Any GM 205 can be converted to the 32 spline input so really I'd say find the cheapest one around (4spd maybe?).
