I am currently restoring a 81 Olds Cutlass Calais and I am trying to put a sbc 357 in it but I can only get one side of the mounts to go through (Drivers side). I purchased the Camaro frame brackets from summit which the part # is OER-332648. I originally had the taller mounts and realized they were wrong so I purchased those but I can't get the passenger side to go through, the stud will go in but it's slanted. I don't know if its the mounts on the chasis or brackets, or do the mounts on the body go a certain way, I was assuming it didn't matter. I have the g force crossmember for the 350 turbo. Just can't get the block to mount completely, I know you don't have to drill b/c the forums say it will work. Bottom hole of mount is hanging off like it is supposed and I don whiggle so much..Need Advice
