This photo, more than any other, shows the aluminum plates mated up to the wood stringers nicely. I'll probably add some additional bolts, but for now things are looking mighty fine. The reason I didn't just make up another wood stringer, was the fact that I was afraid the other one would break in the same place. Therefore, I decided to reinforce both of them. I am very sure even the repaired one is now stronger than the original construction.
All of that is now done, thankfully. I can now concentrate on spinning that motor back around, placing it back on the stringers, and getting that new transmission (and the good exhaust manifolds) all bolted back in place. That should make for an exciting day (tomorrow) !
