The mount is a 304 SS sheet that goes down to 3 or 4 water pump bolts and has one brace welded to it that goes back to an intake manifold bolt. Mount is light weight but sturdy as tank doesn't flop around at all.

Thanks very much.

Probably what I'll go with. Do you have any estimate how much volume it holds? I've heard that you want somewhere around 2.5 qts to limit how much coolant you lose during expansion. Also, do you just fill this halfway when adding coolant after all the air has been burped out of the cooling system, or do you run an additional overflow tank?

The other item I'm going to add as I'm welded up the front end is a cross bar in the front from the spring towers side to side. I will angle this up slightly on each side and then horizontal in the center where it crosses in front of the engine. I thought this would be a perfect place to mount the expansion tank and also remote Oil Filter assy. I have 1.25" square tube 1/8 thick that I was planning on using. I will weld this to a plate and it will bolt in to each spring perch tower on each side so it can be removed for engine service etc. This bar will also stiffen the front suspension as it will not allow inward/outward movement or deflection of the upper/lower A-Arms during hard cornering.

I've seen on the forum where a few other members have added this to their cars and it not only stiffens the front end, but also provides a rock solid mounting point for engine accessories like expansion tank and remote Oil filters.
