I apologize, never checked the rear end gears. I was told 3:73, but could possibly be 3:55 or a 3:55 rear that the gears were changed.

No need to apologize...the 3.55 ratio was the 'default' gear for the L78, but you had to order the posi option. There are some cars that folks ordered a milder gear like 3.31, but they are rare. The axle code should be CBT for a 3.55 posi. Gear swaps were common back then, usually to a 3.73 or 4.10...the motor really wakes up with a little more gear.

A 'correct' missing motor will be easier to find than the tranny...the CW coded TH400 is kind of rare...I have only seen a handful for sale over the years, of course you can build any good TH400 to the high-perf specs.
