SR-4 to TH350 swap started-

OK well the swap really started in December when the clutch went out on the SR4, or so I thought. Turns out the front bearing went out on the SR4 and in turn killed the throw out bearing.

I have been collecting parts ever since-
700R4 to NP208 adapter (I have both the short and tall available now)
TH350 - I also have two of those now- the one I am putting in has all new hard parts, full manual reverse valve body
27 spline input shaft for D300
Twin stick kit for D300 (while it is out, right?)
B&M ratchet pro shifter
2500 stall converter
flex plate
trans cooler

Going to start tearing down the D300 this weekend. Other than coming up with spare funds for the project, getting the input shaft was the hardest part- took two different orders and two months to actually get one.

Wish me luck - never done anything like this in the past.

I bought the CJ7 with an SBC already installed using an old AA adapter and a Chevelle bell housing. Not sure how much abuse the PO gave it, but I only managed 300 miles on the SR4 before it gave up the ghost. All easy street miles too, because I knew it was a ticking time-bomb.

1994 Jeep YJ : 3.75" of lift, 4.56 gears, 8.8 w/ lsd, 34X10.5 TSLS and some other stuff. 4 Angry Squirrels and proud!
1981 (with some 80 and 84 parts thrown in) CJ7 under restoration. SBC 350, 2.5" lift, half hard top and lots of fun!
