Shimming Trailing Arms....for a Dummy!

OK, so ya'll know that when I removed my Trailing Arms to install the new GoodParts adjustable brackets, I foolishly let all my existing shims (and there were a lot of them) fall to the floor without making note of what went where. Not a good thing. So now I need to reinstall the TAs and I need to figure a way to shim the brackets so that the things are reasonably lined up. I bought a bunch of new shims from Moss, theirs are kinda neat in that they are a double shim that slides in from the side of the bracket and engages both bolts, unlike the OE shims that slide in from the bottom. Anyway, the question is, is there a reasonable way to randomly place shims and perhaps measure the face of the trailing arm flange where the hubs bolt up and align the TAs with, what?, the axis of the car?, the frame?, the universe? I will eventually get it to an alignment shop (30 miles away) but wonder if a fully torqued bracket can be loosened with the entire suspension in place on the car and the big honking spring pushing, without all Hades breaking loose. Back off just enough on the bracket bolts and pry with a screwdriver? What a quandary.

Front axle centers with wheels straight ahead? Without a session on the alignment rack it'll be "b'guess an' b'gosh", sorry to say. You can get ~close~ with equalizing toe-in but it could still be out end-to-end and result in "crabbing".

...and I thought the original shims slid in from the side, too? Can't recall for certain but seem to remember that. TR6 rear suspension repair was rare around here.

Wire-ties and zip-lock baggies with a "Sharpie" pen need to be in your toolbox, Bill. :devilgrin:

At least the "adjustable" brackets give you a camber choice. :smirk:
