Driveshaft Questions (clarification)

[PantherRacer]

I've been searching through the 65 pages of results for the word "driveshaft" and everything is a vague reference to aluminum 1-piece from so & so company, custom from this shop etc.

I need some specifics, especially for my situation. Now I'm doing a VQ30DET swap, but I'm planning on either using a VG box, or RB25 Box with VG internals. The car just had an RB swap taken out (sadly, also the driveshaft) but the diff & half-shafts are still in.
I need to know the specific parts used (which nose/tail), or how long the driveshaft needs to be with the RB/VG trans.
If there is a shop that makes & sells them pre-made (such as if I can order a McKinney shaft) that'd be good.
But seeing as I'm all the way here in the Bahamas I'm most likely going to have a custom one made, though I like to keep the options open.
If it matters much it's for a Zenki S14 Silvia.

Thanks in advance.

VG and RB trans will not fit on a VQ30 engine the bellhousing bolt pattern is completely different. You need to use a VQ trans from 350Z,G-35 or the truck. Drive shaft yoke for the VQ trans is also different.. But we have them...

The VG/RB trans will fit, it needs an adaptor plate or the flange welded on from the VQ transmission. It's going to be quicker for me to source one of these transmissions so I can get my car running, and if I sort it out correctly it should be a cheaper route. I do plan to go 6-spd eventually, but unless I get the money I'm owed before I complete the build I'm going this route.

If you guys can help me make the swap easier with mounts/driveshaft/trans sourcing I'd be overjoyed for the assistance seeing as I'm trying to start up a shop of my own over here. Of course I want the first official shop car to be as presentable as possible when finished.
I'll be shooting you an email soon
