Theres some in CA for sale. the one on the right is technically a 542, but its not the "Classic" style, it needs some love but its operable with a 440 and 5 spd, the Sno-Cat next to it is a 1600 I think and its got a 318, both need attention in the track dept.
for more info call Jeff Fleming at 209-795-4335, hes a real nice guy and tell him you saw 'em here.
theres more info on these in another thread here about a page back.
Here
Oh, and welcome
Eric
