Can I use a complete F-body (Camaro/Firebird) rear end?
Yes, but first you’ll need one from an ’82 or newer car with the torque arm suspension. Then you’ll need to have it narrowed if you’re not using the wide IMSA body panels. Make sure the brackets end up in the right place! Finally you’ll need to modify the torque arm mounting area. Roger (monza_madness) gives more details: “The stock F-body (3rd gen 1982-1992) rearend will fit an IMSA panel Monza using 10″ wide wheels with 4” back spacing. No shortening required, just relocating the H-body spring perches and H-body control arm mounts. Widen the H-body control arm to fit the differential housing. The front differential mounting holes have to be redrilled in the control arm. The control arm upper and lower ridges have to be notched, and control arm has to be pulled to a 90 degree angle to the rearend and the ridges have to be rewelded. Careful not to use the German made firebird rearend, identified by finned aluminum brake calipers, as this is a light duty rearend. Also can be identified
