Here it is, the large bolt going up reuses an original hole as a point of reference and the one going down is the correct placement for the z32 subframe. The subframe aligns perfectly and the plates follow the integrated frame of the unibody. The bolts holding it up are temporary and eventually I'll weld it proper. The front mounts were a bit more tricky but it all worked out. I was even able to utilize the original strut towers and had room for the oem gas tank/ spare tire. I ended up going the fuel cell route tho so not pictured.

I have a complete modular z32 rear subframe with custom fabricated mounting plates. It utilizes four through bolts and can be dropped in a matter of minutes. I am also struggling with whether or not to have the mounting plates heat treated? The holes are snug currently but after extended use and road vibration will they start to reem out? Will a quench and temper process reduce this wear? But there's a risk that the extreme heating and cooling may cause the plates to fracture, especially since there are holes drilled in them. Anyone have experience with this?????

Quality information thank you

ok lets talk more about driveline angles because that's my other concern. My 240z has a z32 TT rear subframe swap with the big r230. I have now mated the l28 motor to the VG30DE transmission thanks to a Hoke Performance adapter. The motor and transmission are in the car with the front motor mounts attached and transmission supported by a jack stand. It sounds like I should be more concerned with my height off the floor to keep the transmission output and rear diff in line. The only problem is I just dropped the subframe. Do I need the subframe installed and aligned to do this proper?

Can anyone confirm that the oil pan mounting surface is level? I have the transmission up about as high as it can go and the motor is still angled back but the car is on jack stands so that might be effecting it... Just want to get it right the first time

I got a 240z with l28 swap, I just want to be sure the oil will drain properly.

but is the motor supposed to be perfectly level?

I am swapping transmissions and must install my own crossmember but at what angle should the engine sit? At a slight incline back or should it be level? If someone could but a level on their cylinder head and give me a degree of pitch or just send me a photo of it that would be great! Thanks
