Sure Crower makes them. When I ordered my set, the retailer mistakenly ordered them for me.

I am just lucky enough to have the Summit and OEM w/reunion upgrade at arms length!

I think you need to get the dash number from them for the offset before ordering. Their support is terrific.

Too much weight as in total weight of the car or of the valvetrain? they dont move up except on the axis which is staionary and the resistance is set by the springs. Im sure maybe some how the aluminum would be better just dont think the weight of a fulcrum is reallyu going to make a huge difference but the rigidity would probably be a must have with forces coming ffrom both sides?
