If you cant find a hydro truck bell you can buy a bracket to adapt a normal bell to accept external slave.

With all the struggles of finding a daily driver I want, I might buy an NV4500 off a 95 4wd and swap it in instead of the SM465.

2 weeks today since my Dukes of Hazzard impression, my back is about 80% back to normal. Got out to the shop to do some cleaning yesterday but not much else. Received my hydro pedals from Texas last week so I can at least start making some progress again. Highs are in the 20's all week so not going to get a ton done this week, my shop heater doesn't quite hang when it's this cold.

Rolled the old shitbox out in the snow to fix a wheel speed sensor on my daily. Drove it around the block, forgot the last time it got used it was driven through floorboard deep water and I'm pretty sure I was breaking ice in the axles as I was driving. My shitty sharpie drawing is on the other side.

My 75k BTU that I thought would be overkill definitely isn't. Being that my dumbass dumped diesel in it, it doesn't really like firing up around 0 degrees. Driving the truck just fueled the fire more, unfortunately buying a new daily and having to fix the pile of shit is sucking up all my truck build funds.

Still little progress on either truck. Debating on whether I should continue down the rabbithole of trying to swap springs or if I'd be a lot better off ordering a complete custom spring kit with shocks, shackles, crossover steering, etc from ORD for probably only a couple hundred bucks more than what I've got pieced together elsewhere. Shooting for wheeling this summer in some shape or form, even if it's on shitty 33" all terrains.

Finally tracked down a hydro bellhousing and a good column to swap into the '85. Once I can get that truck pretty well road ready I won't feel as bad about starting to strip down the mostly functional '84.

Got my hands on a column and a hydro bellhousing finally. Can maybe get the '85 roadworthy sooner rather than later. Found an NV4500 for a good price locally I'm going to try to pick up.

Picked up the NV4500 for $650 last night. Dude was telling me since it's replacing a TH400 I shouldn't even have to modify driveshaft length, crossmember or anything, can anyone confirm? The NP208 should bolt right up and I'm pretty sure the bellhousing I picked up should bolt right up too.

Measure the th400 from bellhousing face to trans mount location and compare it with the NV4500. If its the same you should be GTG crossmember wise.. Do the same thing from trans mount to tcase mounting flange on the back and compare those as well to see if the driveline matches up.

It would be pretty cool and make life easier for you if it's a match.

Unfortunately I traded the turbo 400 for the SM465 that's now useless so I'm not sure. I'm gonna start mocking things up soon just for fun. Turns out that bellhousing doesn't seem like it's gonna work without an adaptor of some type.

I have a ‘95 nv4500 bellhousing i’d Trade you for the sm465 one you have.
I need to figure out what I've got, I'm pretty clueless on this stuff. From what I gather there are 2 different style of NV4500's as far as the way the bellhousing mounts.

Advance Adaptors says the 92-95 is the smaller bolt pattern and should be the same as an SM465, so I'm guessing this is a 96+ with the larger bolt spread.

I hate to even ask this but... you 100% sure you got a chevy NV4500 and not the dodge version? could account for the different pattern since dodge used the same pattern as 96+ GM

I'm pretty sure, isn't the Dodge input shaft a lot longer?

This is from memory so double check me but I think its just over 1 inch longer but the tip for pilot is also larger, its 3\4" vs GM that's just under 5\8 so if a 5\8 wrench goes over it its the GM.

Is the T-case flange the same on both? Because the 208 off the th400 looks like it'll bolt right up. Haven't counted splines yet, guess I shouls probably do that.

Ok so it's an older GM NV4500, but the bellhousing is still different than the SM465. The widths are just far enough off.

Thanks to Twankie I should have the bellhousing I need and he should have my hydraulic SM 465 belhousing in a couple days.

Once I've got the bellhousing I'm going to mock the trans up to get the hole cut for the shifter. Going to use whatever metal I cut out to try to patch up the holes it's got.
