Man. I really got a response. Thanks so much. The only number that is on the truck is the one on the left door jamb. There is no tag on the firewall. There was no front end on the truck. There was a big piece of iron with wheels attached. Like a rear axle off of a big trailer. It now has a Mustang II front end with rack and pinion steering. The sheet metal is very good and was a decent truck. No motor or trans when I got it. The front end and the trans and the front end were not a problem because I was going to replace them anyway. You guys have more than answered my questions and agree with me the the assembly is a 51 but the tag on the left A pillar says it’s a 53. Sow 53 it is. I think I have a 53 cab with 51 doors.
