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.
