Yeah, it really is. Forget all those special alignment tools and TIG welders, if you have a cut-off wheel, a drill, and 2 wrenches, you can build the one that I made. I did a T45 swap into a 94 cougar that I had about 3-4 years ago, and I remember when I started looking at it, there was the whole write-up on making the welded-on extension, and I just though that was WAY overcomplicating the problem. I'll stick with a setup like this any day of the week over cutting apart the tailshaft and having to TIG on another box, and have the link only held on by roll pins, and all that other stuff required for the welded on extension box. When I did that swap 4 years ago, I was also the one to pioneer using the SC master with the S10 slave, which also made this type of swap cheaper and easier for other people down the road. Plus if the slave ever goes out, I can have one the next day from Advance Auto Parts for $50, or from the local chevy dealer for $75. I was also the first to figure out back then that instead of spending $400 having an aluminum driveshaft made, or $250 buying a 93 Mark shaft and having that shortened, you could grab an aluminum drive shaft out of a crown vic cop car for about $100, and it would be the exact right length for the T45 in the MN12/FN10. At this point, I have just under $1000 into this swap, including the trans, clutch, flywheel, driveshaft, computer tune, extension harness, tri-ax shifter, and even including the blend door actuator, which was the excuse for this swap in the first place. Plus I still have the recently rebuilt and j-modded 4R70 to sell, so I might be able to pull this swap off for around $500 total cash layout, which would be really cool to me.
