    1. I wasn't aware the early nv4500's shared the bolt pattern with the 465's, COOL!
    2. The 208/241 will bolt up to the nv4500 4x4 tailhousing- must be 32 spline
    3. I have a driver drop 241-electronic speedo, $250 shipped, or trade?

    My NV4500 is a '95 and the bell pattern was nothing close to the 465 pattern.

    I thought I had read they used the same pattern... :doah: Guess I have some more checking to do. But worse case I may just have to get the bellhousing with it. Just want a hydro bell with the external slave cylinder in the end and to have it bolt to a 6.2L.

    Since I already have a 32 spline NP208 I'm going to hold off on buying a tcase till I have a transmission in my hands. Will that electronic speedo work with aftermarket guages?

    What little I know about nv4500's, is that the bellhousing pattern is unique to them. Beware that your rig must be lifted if you're going to use an external slave bellhousing, as the slave is on the lower right hand side, and would hit the diff on a stock application.
    I don't have any idea whether or not the electronic speedo will work with aftermarket guages--probably could be adapted.
    What is your driver drop 32 spline 208 out of? I thought GM used 241's on the new body style 88 up 4x4's. Just curious, always need more information.

    I used a bell from Advance Adaptors. It's machined for a Jeep application slave cylinder on the drivers side. The bell itself was $400 or so...

    i looked for a factory bell for a while, but most every truck that hits the wrecking yard was hit hard enough to break the bellhousings. :doah:

    The only part the NV4500 shared with the SM 465 was the input housing diameter.

    Mine will be going together real soon here, send me a pm and I'll give you all the details of what I ran into as far as what worked and what was a problem.

    And I'd probably do that first before spending $500 on a new bell...

    I had a 465 bell I trial fit on the front of my NV4500 and two holes looked possible, one was in a terrible spot, and one was not even on the bell.

    Maybe the hydro bell's are different?

    Numerous guys have re-drilled the 465 bellhousing to fit an nv4500. All 465 bellhousings are the same to my knowlege. I have a mechanical one bolted to a 91' 465.

    Kenny: I have a 99' hydro bellhousing but it's the internal slave. Supposed to be better or so I was told when I bought it. It fits 96'+ trannies. Let me know if you end up needing one.

    Would be better for space, and would fit the Dodge cummins tranny I found locally... but I don't like the idea of having a slave leak and wreck the clutch. But the Dodge NV4500 I found is cheap and in need of a rebuild anyway. So I will have to think about it, may go that route to keep it simple and keep the cost down.

    How much do you want for the bellhousing?

    I'd take $125 for it. I also have a new GM input,bearing,and retainer that we took out so we could run a GM nv4500 behind a CTD in my brothers Chevy. They would be just what you need. I understand about the bellhousing and troubleshooting a slave leak.

    I have to agree with the apprehension over internal slaves. I had a 98 Chev K3500, 7.4/nv4500; I finally traded it off after replacing the slave twice and the clutch once in 58K miles. Not to mention it was a dog.

    That's odd :confused: :confused: . I'd say something was wrong. I had a 97' 2500 7.4/nv4500 also and I abused the hell out of it,pulled 20K LBS loads of hay and it never let me down. Finally traded it at 148K. It ran like a scalded dog. Would spin the tires in 4 gears :D .
