Yes I'm awareIt sold a few months ago. FJCO has adapters to bolt 8/80-later rear brakes to a 6-bolt housing. You could also narrow a 60 housing.

Similar thoughts, I'd be interested to see how it changes or doesn't the width of the axle. IF it does infact change it, then it's not even a last resort option.That looks like a lot of money for an adapter with no instructions or technical support. Seems like would need custom inner axle shafts that are longer and would need to keep the bearing race in the same location compared to the diff. Would still uses the C clips. Then have to source backing plates/brakes and hand brake cable which is the biggest advantage of the 8/80+ axles. A lot of money and work to end up with a semi floating rear axle.

Yes, I don't want to install a drum parking brake on an h55.Roma,
Just curious on what your end goal is with this path. Rear drum with ebrakes?
Thanks

It may not require new inner axles. The backing plate may be offset to make up thickness of adapter. Do have some early 70s backing plates and 8/80+.backing plates to compare. But I would be interested in this conversion. No.manuals or technical support makes me.womder why. Liability?

I would be shocked if they require new axle shafts.
Keep in mind not all 8/80+ 40 series rear axles have a drum hand brake. Have a HJ47 rear axle without a hand brake.
Years ago bought a set of 67 axles locally that I split with a mudder back east. The seller could have used these adapters. When I picked up the axles he asked if I wanted a box of parts. In the box was some fine spline lockout hubs, Super Winch I believe. Plus all the brakes for a 8/80+ rear axle. That included backing plates and hand brake parts. Comparing one of these backing plates to a early seventies backing plate. The offset between the two looks like these adapters would work without new inner axles. Still seems like a lot for two blocks of machined aluminum.
The brake parts (backing plates) are easy, same as 60 series which I have a few sets of. I've bought a few of these in the past (full float) from Australia and most of the 45/47s use the parking brake on the tcase while the bj42 have the integrated parking brake.
Those brackets are easy. I made some and documented the process in the 75 build thread in my link.Long story. I picked up a 40 series FF in Central Texas back in September of last year very cheap.it was out of a 81HJ45 what I was told
It did not have the rear ebrake. I bought all the toyota backing and the ebrake parts from a 60 series and of course bolts up.
When I was getting ready to order the ebrake cable, then it was a hard realization that the axles housing was missing the two brackets. I as thinking I'll just copy them and weld them in. First pic below are the missing brackets. If some has a junk bent housing and would be willing to cut them off cleanly, it would be of interest

Just find ya a disc brake 70 series rear axle, move spring pads, bolt er in......Full float, uses common 80 series brake components, has the mini drum emergency brake....Looking for a single wheel cylinder, 4 bolt backing plate rear axle in 40 series width. Full float or semi float is fine.
Thank you so much RomaThose brackets are easy. I made some and documented the process in the 75 build thread in my link.
I would encourage you to try to machine those in the US with current material prices for less. I'm surprised they even care to take the time to sell them. They even put the blueprints up for anyone to copy. No one will.
the only thing on a 8/80 rear axle that isn't available new is the housing. This solves that. Do you know where to buy 8/80+ rear axle housings in the US for <$500? I sold my 8/80+ axle for $1000 last year, but ended up refunding the buyer $500 because it needed everything replaced

Parts are not cheap....if you exclude the drums and axle parts I think 4-500Curious how much for all the 60 series brake parts from the backing plates out? I have three 8/80+ rear 40 series axles. Two FF and one semi floating. The three cost me $1K. This was in the last six twelve year range. 40 series is nothing new to me. Know nothing about diesel nor do I want too. But have pretty good idea on the rest. I seena part I know is rare I've bought. In most cases this was after it's been for sale for a.while.
