A couple of questions.

[stilkikin]

I've got a 65 C20 LB stepside with an original 283 with 76,000 miles and a 4 speed with granny. I was wondering what kind of carb I have and where I can get a rebuild kit for it? What can I do to lower this thing a bit? I see a lot of stuff for the C10's but not much for mine. Any brake upgrades? What bolt pattern do I have? I have a new rebuilt TH400 I'm thinking of buying from a friend to make it a little more driveable, are there any issues with this swap I need to know about and will the splines line up? What can I do for the tranny crossmember and driveshaft? Is there a reccomended shifter? Sorry for so many questions but I don't know much about this truck yet.
