I bought a Dana 36 3.07 complete carrier to replace my 2.59. Should fit right? Well I found my first glitch. The new one is from an 84, and mine is a 92. The spindle support rod bolts on the 92 were 1/2". The 84 has holes for 3/8" bolts. The area around the whole on the 92 is larger also. As I...

Has anyone changed the rear ends? I have the whole carrier setup, cover and all to install. I'm putting in a 3.07 to replace my 2.59. Any difficulties I will run into? Do you have to use the leaf spring compressor or does it just make it easier? Would appreciate any pointers before I start...

I'm replacing the wires and plugs. Did the easy side. Now I'm on the hard side. Removed the inside wheel well shrouds. The plugs look accessable. But what do I have to remove to get at the OptiSpark to replace the wires at that end. I can't even see where they connect. The diagram in the...

This isn't on my vet, but my other GM car, an Olds Aurora. It idles OK, revs OK when on WOT to 6200. but when doing 30-40 and give it a little gas it hesitates, stumbles, surges like its running out of gas. I changed the O2 senser. I barely pased my HC and the smog guyu thought it was the O2...

The station done the street started selling 100 octane racing fuel for $4.50/gal. Anyone know if this would make a difference? I have a hypertech Thermo chip. They say it is programed for 93 octane. I've been putting 92. Would it be worth while for racing only? Also my car has been...
