I didn’t know there was any additional harness in the passenger seat. The seats were already long gone when I bought the donor.
I haven't read back through your posts, was anything that prompted you not to use the engine and buy a block other than just to build a higher HP motor? In other words, did you suspect there was something wrong with the LSJ, especially to tear it down?
Is there alot that will have to be done to get this to work with the SS SC body harness?
