Everyone should have in his library the 5/57 ("Plymmie; Fury vs. Stock") , and the 1/58 ("1000 mile test-58 Fury") issues of Hot Rod. Great sources of technical information, including, as per the former: standard PLY T/bar's (and Dodge & DeS Firedome) : 44.6 " 6-cyl cars have 1" bars, standard thickness for V/8's (incl CRL): 1.04"; Fury (& Coro & Roys, which like the Furies, did NOT have sway bars, UN-like the CRL's, which DID have them) : 1.09" . The article states that the 1.04's are are about 7.25% stiffer than the 1-inchers, and that the 1.09's are over 9% stiffer than the 1.04's and 16% stiffer than the 1-inchers. I don't know, off-hand, what the lower control arm working-length is, but it/they were the same on all 57-58 models. The 5/57 article doesn't say what the front 'spring-ratings' may be, BUT... the 1/58 says that : "..the standard passenger front spring [1.04"] rate is 125 lbs/sqin , and that the Fury [and Coros & Roy's; 1.09" ] is 145 lbs/sqin. I retrofitted Coro/Roy/Fury bars (952/953 P.N.) onto my CRL , years ago. I don't know anything about the shorter 1959 bars, but, hopefully some mathematical genius, here, who knows the working length of the LCA, AND the o.a. length of the 59 bars , can figure-out the formula to calculate the spring rates of the 59's. BTW, the thickness of the 300/ADV/IMP bars was 1.11" , but they were longer than the PLY/DOD, @ 48.6" , and they were 40% stiffer than the NY'ers 1.02" bars, but the 3/57 issue of MoTor Trend (has the white 300 convie, on the cover) does NOT say what either model's spring rate was!!--I'm sure it is revealed in some other publication [A.M.A. specs?] ; but not herein. This article does say that the 300's (& NY'ers) 7 rear leaf springs have a rating of 135lb/sqin, "..which is about 50% greater than those on 'standard' [which ONES??] cars."
