...and FWIW, I found the very same mix-up on a rolling chassis I bought
a few years ago, which gave the rear wheels WAY too much positive cam-
ber, although it was exaggerated since the frame was bare except for
suspension, steering, and brakes & wheels.
Lots to check, and double-check, with the IRS cars, given the years
and POs they've been through by now !
BTW the CV shaft replacements for the splined half-shafts sound like
a big improvement to me, although the price is a shocker. As common
as CV axles are for front-drive cars, it seems that an existing type
could be rebuilt & modified to fit Triumphs, or put together with
mostly off-the shelf components, at something much less than $1000. !
But, have I actually researched it ? No. Just noticed a wide
array of sizes, lengths, etc. in the salvage yards that I frequent
to keep the commuter cars going.
