I'm a little confused can you guys help me out???

On a 1993 Nv4500 Will that bolt to sm465 belhousing or do I have to Buy from AA? I want the fork to be on the drivers side.

I have a 1987 np205 round pattern will bolt on to the factory adapter from a 1993 nv4500?
 
I'm pretty sure you need a new bellhousing.... people with more knowlege will chime in soon I'm sure.
 
yeah I read that but it said there was 2 different bolt patterns thats why i was asking. So I would need a new Bellhousing

IIRC the 85+ 205 will bolt up with factory adapter right?
 
The 465 bell won't work without some machining and or welding mods. If i recall right the NV4500 mount holes end up outside the machined area on a 465 bell...at least one or two of them anyways.

The AA bell has two bolt patterns, and gets the fork on the drivers side.

If the 205 has the 6 hole pattern it should bolt up. You may need to oval one hole on the NV4500's output adaptor/housing as the 6 hole pattern is not symmetrical. It is the same 6 hole pattern the 205 would have, but it is mirror image as every factory case that was ever behind the NV4500 was drivers drop.

This is the gasket oriented correctly sitting on the 203 range box that was re-drilled for the 6 hole pattern. The 203 was re-drilled for the passenger drop 6 hole adaptor. Two things you can see...at 8 o'clock you see the one hole that is center punched but not drilled (for obvious reasons). Second thing is the hole at 4 o'clock.

Here is the same gasket flipped over...

I elongated the 4 o'clock hole in the NV4500 output housing...5 minute job.

No problem, hope some of the info posted helps you out. It's not a hard swap, just some of the little details that can trip you up. The re-drilled 203 face had me scratching my head for a while. NWF used a GM 6 hole adaptor as a pattern for the re-drill, so there was no way the pattern could have been messed up. Eventually I realized GM mirrored the pattern for the driver's side drop behind the NV4500. :doah:

Easy fix once I realized the problem.
