you use a LA flywheel on the older LA engine.

Check

your good with the old clutch/bell/linkage as long as the nv4500 and the np435bell shares the same bolt pattern.

Check

the 92-93 nv4500 has a 19 spline input with a 30 spline output shaft = 727-7260 slip yoke works fine.

Check

You need a new 19 spline disc with the rest of the 4 speed fly/pp/tob

Check

for the 2 piece drive shaft? does it have a slip yoke or bolt on yoke for the np435?

Bolt on.

If it IS slip yoke just have the front 1/2 of shaft cut 2"

Check

I may have the stock nv4500 slip yoke for a 7290 joint if you need it.

Thanx Good here.

the top plate and shifter tower change on the HD 10 spine units sometime after 93-94 IIRC so keep that in mind when looking.

the shifter is ok but does not mount up like the np435 shifter.

Look for and older trans

Finding the thing is the hard part.
Check

look on ebay = ManTrans in Tallahassee. Fl. has rebuilt ready to go nv4500 with 12 month 12,000 mile warranty for 900$-1200$ + shipping

drop it off at the door ready to install.

Thanx for all this. Here's a virtual toast for your time spent helping others.
I will be copying all this down for use when I start my search.

I saw that $1200.00 drop off deal
I will be looking for something a little cheaper.
I have free options looking me in the face every day.
I just would like an extra gear at speed.
