I need help reassembling my truck

[edflores]

First off, I started with a 65 chevy long bed complete truck,
Then I picked up a 64 long bed frame with a 62 BBW cab sitting atop, not mounted. After that, I bought short fleet bedsides. Im putting the 65 front sheet metal, 62 cab and short bedside together with the long bed crossrails on top the 64 frame.
My issues:

1. I lost the majority of the front end bolts. I didnt take it apart myself so i dont know what kind/size go where and in what order. I need a guide, and a lot of the bolts sizes. Does anyone make a bolt kit?

2. I need to know what bed rails I need for my shortbed?

3. I lost the rear 1/2 ton cab mounts, and the 64 frame has the 3/4 ton style cab mounts. Anyone have a set?
