WTF \"PICS ADDED\"
So we bought this chev y from a farmer and it seems to be changed. My friend has some questions about it so I will post it on here to insure I dont lead him in the wrong direction
"I just started tearing my 1971 K10 project apart. I opened the rear diff to start cleaning it up and found it wasn't opened, but had a posi or locker of some kind. We started looking closer and found the axle perches are 2" wide (from a car?) instead of 2 1/2" and have some really bad welds on them as well as the shock mounts. But what I really need help with is the gears in the rear, a 12 bolt, but the gears are stamped with a 3/83 manufacture date. So if anyone can help...PLEASE?!?!? Oh yeah the whole gear stamp if anyone can decode it: 1 GM 339635 11 41 3 83. I'll post pictures of the posi lookin thing when I get to work tomarrow. "
The questions we have are
Do they stamp replacement gears with thier production date?
Would there be a factory posi with replacement gears in 83 (the gears have a GM stamp on them so we know they are GM but 12 bolts stopped in 81)
Are cars rearends the same width as trucks?
What dumba$$ would weld 2 inch wide perches on when the springs are 2.5 inches long?
I think those are it thanks for the help.
