I've been a member for a couple years but haven't posted. Been busy trying to hash out things my own way (the dumb way). I've got what is clearly a mutt. It's got a 72 cab, 67 bed, 70 grill, 69 bumpers, an LT1 (Gen 1 SBC), CUCV axles (80s), and late 70s trans and transfer case. I'm pretty sure the frame was originally prepped for an auto trans because the bracket for the bell crank on the frame is definitely home made. I was hoping someone out there could tell me where to get information like where to find the VIN on the frame, how to read it, and also how to find out what engine it originally had in it, what trans, etc. Also, to correct the geometry of the clutch linkage, can anyone give me dimensions and reference points for where the mounts need to be? If you need to know the VIN I can get it in a couple of days. I'm willing to bet this information has already been posted but the internet out here (Afghanistan) is horribly slow and it would take literally forever to find. I'm hoping to dive right back into the truck when I get back. I can't wait to drive my baby again. Thanks, guys!
