Looking for information on finding np205 with 6 bolt round pattern and long input is there a year range or model to look for when trying to fine one?

They are rare and stupid expensive when you find them. What trans are you using? Looks like you have a 6.0 LS swap, did you put a 4L80 in with that? I just used a 3/4" adapter ring to convert the 4L80 index ring to a TH400 index ring size and then used a 6" long 2wd output shaft in my 4L80 cut down to the same ~4.75" long output as the TH400 it was replacing.

Years ago I found a guy on another site that was selling NOS cases. He had a company that converted new trucks into emergency vehicles (ambulances, Fire Dept., etc.). He got out of the business and was selling off his stock. He had about a dozen NOS cases. I bought a brand new 6 bolt round case for $300. Pricey at the time but I was putting it behind a NV4500. In hindsight, I wish I'd bought every one he had for $300.

A 208 or 241 will hold up just fine with 35's, especially on the street.

I know the chain drives are strong but i plan on using as a tow rig and pull goose neck around the farm so a gear drive would be best for reliability just my opinion

It certainly isn't a bad thing to have a 205, but even for those uses, a 208 or 241 will be just fine. But if you want the 205 just to be safe, I ain't gonna argue. I'd be looking at doing the same thing, lol.

Nice job finding one. Now's a good time to consider adding the Twin Stick mod. Your gonna need a shifter anyway, the Twin Stick is worth the effort. ORD has what you need.

They haven't had their twin stick setup for a good while. I think it says it's coming back, but it's been some months for sure.

Why the long adapter with the VSS in it? That's completely useless and will read exactly the same as the OSS in this case. You need either a switch to activate when in 4lo or the VSS on the output of the 205 in order for it to be doing you any good.

I thought that was just the 203 setup?

The JB Fab 205 twin stuck is pretty nice.
