John, I respectfully disagree that it is OK to use a shock absorber as
the rise limiter. That may have been the case on the Corvair, NSU and
Fiat that you mentioned. I would personally endeavor to avoid this
scenario if at all possible. You may want to check with the individual
manufacturers to determine the validity, but I'm sticking with axle
straps. That way I don't risk damage to the shock or the mounting
bolts, regardless of the shock's capabilities.

I also respectfully disagree with this for the following reasons. The
weight and load of the Corvair at the rear - being a rear engined car -
is substantially greater than that of the MGB/MGBGT. It is likely that
the valving for compression and rebound on such a shock would be
entirely inappropriate for this application. Moreover, without knowing
the shock dimensions, it is not safe to say that a Corvair shock is a
viable candidate for fitment on the rear of an MGB.

This is true and like Dave Tietz, I did spend some time looking for
appropriate substitutes other than the Colt option. From what I could
tell, the Colt shocks are the easiest out-of-the-box application. I
would however encourage listers to look for other alternatives as well
and post these to the list.
