SickSix,
No problem bro anytime. The trany is Manual 4 speed. I got a hurst shifter on their and it works very nicely. The rearend is stock. As for the driveshaft I think the only one for the three speed is too short. A guy actully found one for me at the junkyard that fit right in. If you can't find a dirrect fit you can get one at a junkyard that is bigger and take it and have it cut down and balanced. What kinda engine mods. you got, if u are running a Rodchester, upgrading to a holly/webber would be a great start. I love mine bcause its progressive. I can drive good and get about 17 mpg, but If i ride her hard and keep in that second barrel i get about 9-10. Its a mix of both worlds good mpg but still having something left in the pedal when its time to punch it. Don't hessitate if you got questions i'm happy to share, and also curious to what setup u got going on.
