not sure if this was asked but are your t-bars from mopar or aftermarket? the reason i ask is because mopar bars are indexed for heavier cars. in other words, if you buy, for example, c-body diameter bars from mopar they are indexed for a much heavier car and you won't be able to go very low without running your adjuster all the way out. aftermarket bars, or at least the ones from firmfeel, are indexed for a-bodies (i.e. lower) but still have the spring rate of the heavier c-body cars. that info provided to me by dick at firmfeel. hope this info does'nt muddy the waters further.
