TH350 with 6 bolt t-case adapters...

[Hickey]

Which years did the TH350 come with a 6 bolt pattern on the t-case side? I know it started with the NP208...

Never, they always had a 4-bolt pattern. The NP208 uses an adapter.

And yes, you can use that factory adapter for a D300/Atlas, but it takes some reworking. They're also usually sold for way too much money for a junkyard-type part.

I've got a 700-241 adapter laying around. I've heard it will work for T350, but I don't know (and it would probably depend on the T350-short vs. long tailshaft).

That's what I meant, the adapter pattern on the t-case side.

I also have a 700r4 to 208 ? adapter taking up space

but how do you change the 27 spline T-350 output shaft to mach the 23 spline dana 300, i mean AA sells them but is there a way to swap it using junkyard parts, jason.

I bought a 27 spline input from Novak for my 700-D300 setup.

What Mbryson said, you change the input on the t-case.
