Thanks, kansas -- hadn't been on Jack's site since he added that part number to the listings. I'm sure he's done his usual good job on the engineering and directions, so I think that'll be my fallback position if I can't get results from the lever shocks.
I'm kind of interested in seeing what I can do with the lever shocks, though, since I've never worked with them before and they seem to be "controversial" (lots of strong opinions on the Brit-car boards) so I'd like to find out for myself what the scoop is. Some people say they're crap and you absolutely have to get rid of them; others say they're fine if well-maintained, so leave them alone. I got a box of extra ones with the car, so I figure I'm in a good position to experiment!
Apparently (from what I've read on the Triumph and Morgan sites) there are two avenues for tuning the lever shocks:
-- You can change the weight of the oil, using different weights of motorcycle "fork oil" or "suspension fluid" (different products; come in different weight ranges.) Apparently the original Armstrong oil was something like 5W, but the motorcycle oils are available in a range of weights. The Triumph production race cars of the '60s ran stock lever shocks with 30W oil in them, so I figure that's a realistic upper limit; I thought I might experiment with 10W and 20W oils and see what kind of damping I get.
-- You can tinker with the valve, which (so I've read) can be removed via the big hex at the bottom of the shock body. The jounce and rebound damping have separate valves, and supposedly you can tweak these by putting shims under the springs that hold them closed; this would let you add rebound damping without changing jounce or vice-versa.
Anyway, I figure I'll play around with my spare shocks a bit and see what I can find out. At least it's something I can do indoors when it's too cold to be out in the garage this winter...
