So far from skimming the boards, I have noticed that most people go with a mid 80's 4-speed or T-5? from a S-10. I am open to any suggestions that you folks may have. I am basically looking for something that is going to bolt on without much fabrication, because I no very little as far as modifying drive shafts, etc.
thanks in advance

Most of the 4 speeds shouldn't be a problem. I have a M-21 but the first gear isn't low enough to work well on my truck. You'd really want something with overdrive too if you could get it. I've heard good things about the Super T-10s. I'm afraid I can't offer you much more than that. I hope this helps.
BIGGY--What rear gears does your '65 have? My truck has 3.73s and I've run my 250 up to around 75mph. Just curious.

Easier install than the T5, it bolted right up. I'm really pleased with it (8000 miles now since 12/02), cruising 80mph no problem and getting 20MPG on the highway (16mpg in-town).

I have a four speed on the floor but way too many hills and stop signs to make it enjoyable...anyone up for a trade?
Use a big enough catapult and even pigs can fly...remember nothing is impossible, impractical yes, but never impossible.
