    From the things I've read it's pretty straightforward, but as 77 said...I'd ask Hotrod or Offroad

    Started you a new thread. This is going to end up with really good info.

    I know it can be done. The SM465 that I bought, was from a guy who had an 87 Short Wide K10 4x4.
    He also said he loved it, and he got the later model NV4500 so that the wide ratio between 2 and 3 was taken care of. Back in the day when NV4500 came out, all the offroaders wanted it badly. They got it, then realized they didn't like it so much because of the wide ratio. Apparentl that has been corrected in later years.
    I have seen some info about this, and will try to dig it up.
    What are you swapping from as far as what type trans do you have now, and this a 4x4 or 2x4 truck you are wanting to make the swap?

    I'd like to see what C4 has to say about it, in the mean time, I'll be looking for links for this swap. Also 83K needs to let us know if he is currently SM465 or auto? What I do know already without even looking, is IF he is currently running a SM465, he can use the same clutch set up, but will change the clutch disk. He can also use the same bell housing but it'll need machined to a bigger opening to allow the input shaft nose cover to fit the old bell housing since its bigger on the NV4500. OR replace the bell housing all together with updated unit. Also, if he is SM465 or auto for that matter, he will need to acquire a Tcase adapter. As GC said, its pretty straightforward, just a matter of acquiring the right parts to bolt in. There is no fancy machinging needed, or fabrication needed I know. You can even use the same Tcase crossmember. Those are the things I know about swap so far. I'd love to do it, IF I had a vehicle that was already SM465. If not, I'd want to acquire a vehicle that is SM465 to make sure I have all the correct linkages, pedal, bellhousing etc. And having the bell housing machined should not cost but about $20. IF you were careful, you could probably do it yourself with a deburring tool. It might not be perfectly round, but it doesn't have to be just so long as the trans bolts up.

    My 83 k5 is what I am curious about swapping the nv4500 into. It's 4x4 an currently has a 700r4 in it. I thought I read somewhere that the 700 crossmember can be reused and even the drive shaft wheter it's true or not im not sure

    Many times the crossmember can be reused, its just a matter of where your holes line up and you might have to drill new locaiton holes in the frame flange. I have not done this swap personally, so I can't say for sure.
    If the NV4500 is longer than the 700r4 Set up, then sure, you can use the same driveshat, but it might have to be cut down. If the NV4500 set up is shorter, then your better off the have a drive shaft made, or find a longer one and have it cut.
    Do you currently have a single piece or 2 piecse dshaft?
    I can find you the dimensions of the 700r4 since I have those. But we'll need to find the dimensions of the NV4500 and Bellhousing assembly to make the comparison to know for sure.

    You're doing this swap in a K5 Blazer Correct??? Are you intending to use your same Transfer Case? Or are you intending to purchase an NV4500 with the Tcase already married to it??? Beleive it or not, this is going to be an expensive adapter, so it might be best to try and find a NV4500 with Tcase married already. You might end up ahead of the game in more ways than one doing so.

    So the NV4500 is 12.37 inches in length, but now we need to know what the bellhousing dimensions are. Also brings up another question. Are you going with a manual linkage clutch or going with the hydraulic set up clutch. You'll have to acquire the correct bellhousing for the proper clutch type.

    I believe I have a single piece driveshaft, yes to swapping into a k5 and I would prefer hydraulic clutch. If I find a tranny and tcase together I'll use it if not I got the 208 and a 241 to use if they mate.

    OK, so you got that part planned out as far as the clutch. And yes I reread the thread instead of skimming like an idiot and relized its a K5 so yes its a single piece dshaft. Good new there is, IF by chance you do need a longer shaft you can alwasy use one out of a long pick up and have it cut down for alot cheaper than having one made.
    Have you acquired your hydraulic clutch pedal and linkage yet??? May as well get the brake pedal off the same truck too when you do, or you could cut your current brake pedal, but I prefer the OEM factory look so I don't get into that redneck butchered up look at all. JMO on that. The reason I suggest finding an NV4500 that is already married to a Tcase is for cost reasons. That apapter for the Tcase is likley to be about $500 or $600. So if you found a NV4500 and Tcase already married, for $800-$1000 you're ahead of the game. But, now I am wondering what year did it get more common to find the electronic Tcase in GM trucks, cuz I think you want to avoid that. I know 95 was still using the stick. I had a 95 6.5 TRubo Diesel 3/4 ton with NV4500 and stick shifted Tcase, just not sure what Tcase it was since I didn't have it long enough to need to work on it.
