Hooker P/N: 12621HKR mounts
Anyone use these Hooker LS swap motor mounts on their conversion? Tennessee Speed Sport told me about them, said I wouldn't have to change my frame mounts with these Hooker swap mounts. Evidently they bolt to the LS block and act as a clamshell.
Just curious if they work and align the drivetrain properly. Meaning if I use a Spohn T-56 crossmember it'll line up without any issues.

12621HKR (MOVES TRANSMISSION 1.25” FORWARD AND .5” UP FROM STOCK LOCATION)
NOTE: This 12621HKR engine swap mount kit is designed to locate a GEN III/IV (LS Based) engine so that the transmission bellhousing is located 1.25” forward from its original position when installed with a standard small block Chevy engine using stock clamshell style mounts.
NOTE: Due to the engineered raising of the engine by .5”, the rear pinion angle may need to be modified if increased drivetrain vibration is experienced after installation.
I don't think that's what you want.

Just grab some of the 1" setback plates that various vendors sell. allows you to reuse the upper and lower mount pieces and puts the engine in the correct positioning for trans/driveshaft
