Working on the shifter linkage....Muncie 4 speed 1972 Corvette

Well so far I have found cotter pins where they don't belong....clevis pins in backwards....The shifter levers are on backwards and the reverse lever is not the correct one.

Tool pouch for the Vette....

Bought this off eBay for around 20 shipped.....Quality is very good and it holds just about everything I think I could need broke down on the side of the road.

Rear end oil....

I'm fixing to change the oil in my muncie and rear end...This is a 72. I'm going with Sta-Lube 85W90 GL-4 in the muncie. I'm pretty sure the rear end is still stock with around 100,000 miles. I am having no issues with it just need to replace the oil because I have no idea when it was changed last. Bought the car this past May.

Should I stick with GM or is there a better option...?
Are the GM part numbers listed below correct....?

GM gear oil part#89021671
GM posi additive part#88900330

The car will see under 2000 miles a year and not driven hard.
