Default c4 transmission crossmember help

ok..i got a 351w and c4 tranny..i swapped in to replace the 4cyl..motor and tranny are dropped in a bolted up..and i put the stock 4cyl crossmember back in and it does bolt up to the c4 ( i expected this)....so i was wondering does anyone know of a crossmember that would work for this swap/setup? the bolts on the c4 the appear that would go into holes on a crossmeber are to far forward..so i guess i need the crossmmeber to be able to slide forward towards the engine more to reach the bolts on the tranny?

can anyone help me out?

and also i need a crossmember that would allow an X pipe to run underneath...thanks

YOu try a GT or cobra crossover? go to a junk yard and try it out. I know 4 cyl engine mounts and I think the cross members are differnet not sure how but the GT also had dual exhaust so they should at least clear ur exhaust system.

yeah. it says it was modified for a c4though. it looked just like this one.http://cgi.ebay.com/ebaymotors/1987-...spagenameZWDVW .
I think some of the crossmembers you might have to cut one side each bushing and do some welding. but the link i just posted^^ is identical to mine.
