For a friend building a buggy, Patooyee's site is down, so can someone tell me all there is to know about the following axle?

BOM 603690-1
C35832 cast into diff along with 447F

The kid swears it's a '79 but the welded on radius arm mounts indicate an older model, the ring gear is stamped with a build date in November of 1975, so I assume that it is a '76 axle, but the guy he bought if from swears that it is original to the '79 truck that it came out of. Ford using old parts on the assembly line or post production swapping? Either way, I just wanted to look up the BOM for shits and giggles.

Still need this info?
Give me a week and I'll look it up, if Eric doesn;t jump in.

Right now I'm on vacation, pool side in Key West, with a 1/4 full Guinnes at my side. However it is rather chilly on this moon light breazy night, might get into the 70's.

It is possible.

Also N while your in key west, check out Kevin MacSomething( I foget the name) They have the best comic/musicians in there. It's like right across the street from Margaritaville

You are correct. It is from a 1976 F-150 with Full-Time T-Case.
3.50:1 open diff.

Since it has disc brakes it would be a drop into the '79 and someone could think it was stock. But it is indeed a '76.


Eric

i did a quick google for this bom# on an axle my brother has before buying parts and came up empty except for this thread.are there any current decoders for the older axles?
