I have my eye on a used GV unit from a 7.3l PSD with the NV273 transfer case. Does anybody know of a way to change the GV unit to fit on my BW 1345 transfer case? This is the only aftermarket parts house I know of for GV. According to a buddy of mine with a GV unit in his 68 Mercury Cougar, GV doesn't provide parts, only complete kits. I know I would have to change the output shaft behind the GV unit, but I would also need it to work with my transfer case. Any ideas?

When i put my gear vendor on, it was a near complete kit from a junk yard. I called up gv hq in California. They were quite nice and informative. Of course they tried to upsell me new kit stuff, but in the end, they did sell me just the parts I needed. They even dug up an old yoke from their old inventory for me. They also got me an installation guide and new seals.

I'd call them directly. They can answer all your questions.

 

Thanks for the info. I will post pics if I buy it.

So, I just called GV directly and they quoted me a price of $650 for a coupler and $1150 to exchange a used GV unit for a new one. Hmmm... maybe I need to go shopping this weekend.

 

That could be worth it. My GVOD is invaluable to me. Bringing down those RPM's is good for the engine, and with that doghouse, it brings the engine noise way down. I can have a conversation with a passenger! Imagine that!
