4-Lug 8 Inch Rear End

Considering you are still running the 170 (according to your salutation) unless the 7.25" is howling or failing in some other way - which can be hard to repair due to the woeful availability of parts for it - you should just run it or collect a few more of them to act as a stock-pile to replace them as they fail, or to build the best of a few. I see more of those offered for free to nothing than any other rear-end out there.

There are a few of us who have installed the 4-lug 8" without any modification, but that 1/4" on each side if it were to be a problem could be assuaged by rolling or trimming the rear flare to take the edge away.

Not quite with the 170 anymore Roger, guess I really need to do updates. I'll post it in my thread that I rage quit on, see if I can redeem myself a bit.

The real problem I've had is finding one of the 4 lug 8 inch rears. It's been a few years now and just nothing. I've got a lead on two 'maybes' but they’re on the east coast. The junkyards will not inspect the axles to accurately identify and want me to show up in person to do my own checks. That is just not workable for me with the cost.

There might be one in Idaho but I still need to hear back from the junkyard and it sounds likely they will not check, just confirm that a '71 Maverick is there. It's been incredibly frustrating.

I can still put the car on the road after the engine rebuild though, which is good.

You might consider a 8.8" cut own to fit. I'm not sure if they had any with the correct 4-lug setup, but maybe. It's a pretty common Falcon add as it seems if you remove the long tube and axle side and cut down the length of the short side and get another short-side axle shaft, it fits a Falcon. There is probably a specific model you need to start with (I know DogHouse here did one on his 63 Sedan Delivery back in the good ol' days).
