Np231 adapter to th350

[Peterbilt]

I'm looking for a used adapter for the np231 21 spline to th350 ... I know I'm looking for the impossible but I still have to ask

Consider rebuilding your 231j using the front half of a 231c if the t350 output is the same as the 4L60e, this is what I'm doing in my Jeeps.

That's worth checking into thanks

You'll want to reuse the shifter pawl from the 231j, along with the internals and rear case.
