Shelbe1991

I have a few questions about my LT1 swap i'm doing in my 1992 GMC Sierra. The engine is out of a 1995 firebird, and is goin into my 1992 GMC 1500 Sierra. I know the motor mounts fit, as well as the flywheel and manifolds, but I am curious as to how to re-arrange the wiring. And also, the brackets for the engine that were previously on it wont fit, and neither will the brackets on the LT1.

Does anyone know of any kind of custom brackets for this particular swap? And what can be done about the wiring?

Thanks,
Ryan
