1960 K5 SM 465to NV 4500 swap

[Green mtnk5]

Can anyone help me with what I need to do with the crossmember. I need to do to finish this swap to the NV4500?
Do I most likely need to get new front/rear driveshafts?
Im definitely an amateur at this but love my K5 and im trying to get it on the road!

thanks so much

Bob

I'm pretty sure the 85-91 crossmember is a direct bolt up for the gm nv4500 swap. And you should bet on shafts unless it has a 85+ trans and tcase combo in it now.

good to know 85-91 works
could I move and or modify existing crossmember?
(I have a NP205)

Depends on what crossmember you have now.
But likely make a 4" tall spacer and bolt it to the nv4500 adapter housing and use the OEM crossmember that came on that truck.

Cracked screen on the phone hence the 1960 typo...

I have pictures of swapping an NV4500 in my Blazer thread (link). You didn't say what crossmember you're starting with, but it's probably just a matter of building a spacer like I did.

And, yes, you'd be redoing driveshafts if you're coming from a short SM465 to a long NV4500. '85+ SM465 trucks got longer adapters that made their transmission length equal to that of a TH400/700R4/4L60/NV3500/NV4500.

What are you using for a transfer case?

And nice truck!

Hi campfire,
well its done. 2 pieces of square tube 1/12 steel stacked and made a 3 inch spacer.

didn't have much time to drive it much with work and all but can't wait to dial it in more.
