My take on the R2 4 speed. 1) proper replacement of hog troughs is $4-$5k, proper strip, body repair, replacing all rubber after removing all glass between $25K & $40K, redo transmission $3 to $4K
do all guages work? what is the condition of the dash? The dash alone is a $5K expense
Another words, to really do that car right, expect $50 to $70K . Chrome would be included as rebuilding supercharger.
You have $90 to $110K into a car that is probably work $100 to $110K
