So here it is.
Dual pass, dual core construction, and 3" thick.
The price is $329 plus shipping, and comes with the mounting hardware and a new radiator cap. This will work with the stock radiator hoses but the bottom hose needs to be trimmed and rotated.
It has a fitting for the water level sensor and the heater return line.
This will fit any big radiator car (S3 an the 83' w/ the behive) and should fit the S1 and S2 as long as the oil cooler has been relocated.
If you are interested in one for you car just let me know.
