What’s it worth? Odd 69 Swinger

I think it's worth as much as a column auto R4/black 318 Dart in same condition, plus open market cost of 8 3/4 open rear end, plus cost open market value of complete core 4-speed conversion.

I'm canceling out the labor dollars to install the 4 speed conversion and buildsheet/fendertag value with the package discount of buying car, 4-speed, and 8 3/4 together.

So I'm thinking add $800 for rear and $1750 for 100% complete trans conversion (no new or rebuilt parts)
