I agree NV 4500 will not fit. has its own bell housing for the 5.2/5.9 engines.

that is a hydro bell 88-91 v-6 or 318/5.2

435 4 speed
a535 5 speed
833/833OD 4 speed

will bolt to it. mine is from a 88d100 v-6 a535 5 speed.

I used the v-6 flywheel on my 91 318 with the NV4500 hydro bell and NV4500 5 speed.

great score!
