I've recently bought a '84 F-250 truck and I'm trying to find out how the truck was built up.
It has the 6.9l engine and today I discovered it has the C9 tranny.
I'm trying to determine what rear axle it has ( it's a 4x2 ) and I found the following numbers. Unfortunately, the plate is hard to read;
44O 4TA-BEC
60205
Is anyone able to figure out what axle and diff it has?
The plate in the door says "Axle #72".
Does anyone have a clue about this number? Im back working on the truck this friday but I don't think I can find any more readable numbers on the diff.
Sorry for the wrong info.
I indeed meant a C6 tranny.
The gvwr was wrong too. The label in the door says 8800lb
I will make a pic of the diff tomorrow. It's a 10-bolt diff.
Any chance I can verify that it indeed is a 4.11 if I open it tomorrow?
Unfortunately. I figured out that it's an open diff. I was parked on ice with my rear tires and I could hardly get out.
Are there any sets available to modify this diff to limited slip diff or would I need to change the whole axle?
