Hi and welcome to the forum. Not knowing your experience level,I'd recommend a fully engineered kit such as Fatmans, but there are others that sell them. Shop around some more and get more informed. There are several threads here about installation,look them over. Perhaps Fatman has re-engineered his kit so that clipping the framerails is no longer necessary. There is always a camaro frame clip,which inherently gives you the engine mounts you want. Get a few books on the subject and study up. Hank
