Did not know parts were missing in june. Thought would be together and all ready raced a few times by now and would be putting my 11 sec motor in about now.
What a crummy year weather wise also.
Is there any reason the older style crossmember will not work if you got the older style mount? It might make the search easier. Are the bolt holes in the same place?
I always cut the outer area of the crossmembers off on street cars so I can drop a transmission with out without unbolting the exhaust. They end up with only one bolt hole on each side. I have never had any problems at all.
