It's been a pretty good truck for the last six years. You can still get OEM parts. I've gone through two transfer cases and a third member and found them in salvage yards on the internet. With the engine swap I'll have all Toyota running gear. If I had known at the time that I bought the Rocky the stuff that I know now I would have bought a 4Runner. But one thing leads to another and another and another and now I have too much money wrapped up into it to start over. I have heard that Toyota owns 51% of Daihatsu Motor Co., Ltd. Take a look at the rear axle as it looks like a Toyota 7 1/2".
As for the SAS I used the stock Rocky steering box, rear flat springs and the Daihatsu drive shaft flanges mounted right up to the Toyota thirds.
Don't have any good wheeling pics but here's a side shot.
I keep telling myself that it kinda looks like 2/3's of a 4Runner...good luck with the swap.
