Yes I have a G80 according to the codes on my glove box. I think it's 10 bolt 8.5 in, I will double check before ordering the gasket. Thank you for the info.
I was looking to do the same thing and I used facebook market place. I got several hits but the guy that is 16 miles from me was the most legitimate. Several people responded but this guy was legitimate. We're doing the swap in Jan 22. I hope this helps.
I'm getting ready to do the exact opposite. I don't like the loss of cargo space with a fleetside and I have a local friend who wants a stepside. While I'm doing this I'm going to put in a new gas tank and pump assembly. Spectra makes the whole kit in one assembly along with new straps.
I have a 1995 K1500 5.7L ext cab. The owners manual calls for 80-90w gear oil in front and rear axle but I have read that 75-90w will improve gas mileage and it's better in cold weather. Has anyone used 75-90w in place of 80-90w without any issues? I plan on using Amsoil Severe Gear either way...
