Very rare behr magnesium race thermostat for usage with large oil lines. (914GT or 917 would be suitable)
These have M30x1.5 openings and has a mounting tab on the back for mounting on the inner fender.
The housing is magnesium and shows no signs of real usage, even the edges were the copper or aluminum seals go are evenly colored and not shiny from tightening the connectors. I've bought a set on new aluminum M30xM30 for it, you can also use steel ones if you need longer treads for mounting your lines. Alu/copper seals are new.
I've converted a standard 911S thermostat with M22 ports for my 914GT project, this one is a little to rare for my replica.
