OK, first the ZF, if you look up my gallery, I posted tons of pics, a drawing of what my crossmember measurments are and also pics of how the NP205 mounts to the ZF.
The AC is for onboard air, it is a long story about how I got the serp. belt pulley on it. To make it kinda short, I like to make my own stuff, figure it out myself type of build. I accidentally broke the v belt pully on the ac clutch on that old york compressor. Just by chance, I had a serp. smog pump pulley sitting right next to it. It simply clicked on. Perfect fit. It fit so well, it held itself in place, but you could still spin it on the clutch....very weird. Well, I put six half inch tach welds around it(after meas. the location for the weld seperation to be even,,,need balance) figured I would try it. Works great, the oversized balancer on the ac compr. seems to dampen any imbalance I could have created.... has worked great...
The tray. I originally cut out a section of the rear floor pan to put inboard shock setup in that would allow for 25" shocks with only a 2" body lift. Using angle iron, I made a hump between the wheel wells 6"tall x8"wide that span the entire way across to each wheel well. It seemed to be wasting space, but I remembered someone else building a box. So I fabed up this tray.
