whats a good manual trans?????????

[stepside83]

I'm building a 1983 Chevy c-10 2WD, stepside, and it had a 3 speed in it with a 250 i-6, i took all that out and am using a 350 horse 350 v-8, and I'm looking for a good 4 speed, or 5 or 6, for that matter, that i don't have to re build the floor to get trans to fit, or anthing like that, and also doesn't have to be but id like to use a hydraulic clutch, but not a must have, any ideas, tips, links, and pics would be awesome the truck will have 3:73, in rear end, and its going to be on air bags, not laying frame, it ll just be as low as i can get it, with out cutting the body, or bed floor, so anything any one could give as far as the trans and a good one to use, thank you in advanced
