Looking great. One thing I found, when I did my SBC swap, wat that my driveshafts are 1" different in length. If I had mover the engine back 1/2 an inch they would be interchangeable. Now, 29 years later, my rear driveshaft has developed a small amount of play in the splines, and eventually I'll need to replace/rebuild it.
At the time I still had stock steering and the #6 spark plug was barely accessible with a 13/16" socket and a 3/8" universal. Half an inch further back and I'd have to lift the engine to change that plug with a socket and universal. 3 years +/- after I did the swap (1999) I found a spark plug socket that combined the universal and the socket and I had tons of clearance.
Now I have Scout II P/S and the stock manual pedestal is bare... so it's even more of a moot point. When I rebuild the rear shaft, I'll either make it slightly shorter and use a longer slip joint... or not worry about it and it'll be my grandkids problem in 2055... and they will be able to 3D print a new driveshaft... if internal combustion engines are even a thing by then. Hopefully it won't be full on Mad Max by then.
