Re: 1969 American/Jav/AMX Spring rates



" From: farna@xxxxxxx
" 
" I included Javelin and AMX rates just in case you want to mix and
" match springs. As far as I know the SC/Rambler used the optional
" heavy spring rates, which were the same for the AMX. Javelin V-8
" heavy springs were a bit stiffer. Since the 4.0L is a little lighter
" than an old 232, at least 40 pouinds lighter, I'd try the light
" (standard) V-8 wagon springs, or V-8 wagon W/AC at the most. I think
" over 100#/inch would be a bit on the stiff side, and it may sit a
" little higher since you should have no more than 800# on each spring.
" Shorten to about 9.75" to retain stock height, or maybe 9.50"
" (assuming all other stock specs, like loaded hgt. weight).
