Converting to 3 on the tree transmission 283 350 v8 HELP!

[Flea Jr.]

Ok so i have a 65 SWB step side with a 350 and Th350 trans. I want to convert it back to 3 on the tree. (I have started dressing the motor to look like a 283) but I'm am getting the run around on what parts i need. Mainly what size clutch and what transmission i need. I want To keep it as correct as possible for 1965. I have sat here for hours and have only become more confused, some places say its an 11" clutch, others say its 12". Yet another says 10.5"(which I'm sure is wrong) . Dose anyone have pics and/or solid info of what trans and clutch, flywheel,pressure plate, starter etc...i need and would be correct for a 283 with 3 on the tree? Preferably from some one who owns/has worked on a v8 3 speed truck. But any good info, pics or part/casting#s appreciated.
