Thansk a lot guys!
After I read your posts and looked around, it looks like some of the engine crossmembers can't be used becasue of the IFS crossmemeber No Limit has as part of their kit.
That engine mount R-Bo referenced from No Limit is interesting, I think I will give them a call. Maybe it is designed for the crossmember I have.
The boxing plates that came with my IFS kit only go part of the way back to the cab mounts. I bet I am going to have to do like R-Bo says and lower the motor in place, and see where the mounts have to placed.
I may need to have a couple of mount types around and send back the ones that don't work.
Thanks to all for your advice!
