I love the consistent progress! What's next on the list to tackle?

Good looking work.

Good call on the honed out bearings. That may be in my future if the front or rear gears are noisy.

I was under the impression that the gears in my truck were the original gears since 3.73 was standard equipment, and the SPID doesn't list the ratio. I was reading the optional equipment list in the sales brochure for 1971, and it says a 350 engine gets 3.07 gears. My SPID lists a 350 engine. It is obvious that someone has worked on both the front and rear gears on this truck, so it was probably to swap the original 3.07 gears for 3.73 gears.

I'm not claiming to be a total expert, Pat, but from what I've gathered; the 3.73 Ratio was standard for Manual Transmission trucks, while the 3.07 was for Automatic Transmissions.

Hmm. My SPID lists a 350 engine and a 4-speed transmission. Here's the table from the 1971 sales brochure that had me wondering about the gears. The brochure also says that 3.07 will be included with a 350 engine.
