My mind is racing so many different ways, right now, all retrospective, which is never much fun....
In retrospect, I'm nor so sure that 60 front and rear axles may not have been a better "solution", along with 60 PS.
At the point I am now, I almost feel that going to the trouble to source the TC brake would be easier on the noggin', considering that it's the least amount of steps to retrace.
While the later 40 housing is appealing, due to track width and "bolt on" compatibility, about all that'd swap is the third, leaving an entire axles worth of rebuild/reseal components to buy.....again. At least appearances are OE, not that anyone but me gives two chits.
I lack the technical proficiency to make a good decision, at this point, to which y'all are all aware.
Now that I have everything, and I mean everything, to completely redo the 55 front and rear axles/steering (along with a host of other items), considering the addition of the H55/split case, resto "mod", DD only, along with a few other nuances, this might have been the direction that I should've thunk more along the lines of:
60 front and rear axles, complete
60 diffs
60 power steering, complete
60 leafs
Somebody give me a reason that this isn't a more effective way to address all aspects of concern, please.....
Have been through this before on the 80.
Though there are many things I would do differently, all suspension related, I can't think of but a few folks that agreed with me on building the 80 axles, to the extent I did, in OE form.
Second guessed the decision on more than one occasion, yet, today, I wouldn't have it any other way, so that experience does carry some weight, here. (Not the suspension, [ie. coils, arms, and the turd polishing that followed] I still regret my decision there)
