[Healeys] schuttle shake

[Bob Spidell]

Well, FWIW, my BJ8 is an original, unrestored (except for paint) car, and it has 
always had some scuttle shake (from 64K miles when I bought it to 170K now). 
Shocks have been rebuilt (Peter C.), driveline and drums balanced, alignment 
from specialty shop (good one), front suspension rebuilt (yes, correctly), 
72-spoke SS Daytons with Pirelli P3s, Yokohama A321s and Vredestein Sprint 
Classics, tracks true, etc., etc. and it still shakes some.  The shake starts at 
exactly--according to my speedo--at 56-57mph and builds if I stay at that speed, 
and goes away at 59-60.  That's why I believe it's a harmonic in the chassis (I 
think it's been mentioned that Geoff Healey acknowledged this problem--can 
anybody say for sure?).

Maybe some individual cars are more susceptible to the shake, and I have no 
doubt a proper resto will accomplish a lot as the suspension bushings, etc. will 
be renewed.  I've done my best, and still have the shake.
