Just installed a 200-4R in mine, replacing the original TH400. As for sourcing it, I can't help, as I've had this one for years. I bought it from FB Transmission out in New York (they were, and perhaps still are, pretty well known for their 200s). It was about $1800 at the time, and it ran 12s in my 4300lb car. So it took the abuse in stride.

Bolting it up was easy enough. In my case I have the dual-bolt pattern 200, which not all of them are. So make sure whatever you get will indeed bolt up to a Chevy bellhousing.

I used a TH400 mount and it worked perfectly. I would say it was maybe 1/8" out of alignment with my factory crossmember holes, but close enough I didn't have to fab or modify anything.

I picked up a TCI bracket for mounting the TV cable to a Q-jet. It doesn't clear the intake (our trucks, at least the big blocks, have a very low intake manifold) and will require some fab.

In my case I do not have a lockup converter, so no electronics whatsover.

I believe the cooler lines are reverse from the TH400, so keep that in mind.

The transmission guy that I had "refresh" the trans and fix a leak was a little dubious about my using a 200 in a truck. Apparently the planetaries are small. But it held up in a drag race situation nicely and so I'm hoping it'll survive the truck. Make no mistake, though, they're not strong in stock condition. But many builders are out there making stronger variants. Once built most claim they're stronger than the 700/4L60E.

The yoke on the 200/350/Powerglide is different than the 400. Since I had a 400 I wound up buying a 1350 Powerglide yoke only to discover that the driveshaft is also 1350 everywhere -except- the front, where it's 1330. So I'm running a 1330/1350 u-joint in the front. If you were using a stock 200/350/PG yoke it could also be 1310. Short version is once you have your yoke you might need an adapter u-joint.

I have not installed the driveshaft, actually hope to do that today, and will report back if I remember what was required, but at this point I'm assuming the length is close enough to my TH400 that it won't require any modification or replacement.
