Found out the RPO code for my differential is GU1, which means 7.5" / 2.41 ratio unit.

Now that I think about it, is the rear interior upper window molding two pieces? I got these fiber optics housing out of an 83 & an 84 Oldsmobile 98 regency(both 4 doors). The fender fiber optics housings are the same(part number and all) as the gbody coupes but the rear monitor is a totally different shape and location placement.

Got it! 2 versus 4 doors :)

If you have a 4-door unit for sale, let me know via PM.
I'll see if I can find one in maroon color today. BUT I'm not sure if those are correct for the gbody 4 doors. I got them out of a big body Olds 98 and they're the same for the big body Olds Delta 88s too.

today, got this in the mail from gbody forum member Bruce Davis and I'm happy:



A fast ratio gearbox from a GN.

To install soon as weather permits.

Worked a bit on my odd fire V6. Neat rocker arm shaft.

TODAY I bought a 3.73 7.5 locking differential and it came along with a disk brake setup. Will need to understand the nature and specs of these brakes. Not sure how they tried to mount the calipers on this differential.

And more progress on the 231 engine that I will use for my 1984 turbo project.

Got to see the crankshaft, confirming once and for all that this engine is an oddfire type...:


Even if the camshaft looks like an evenfire type, because it's a once-piece type:


Will probably endup using a carburator, not an injection setup. Still undecided.
