bill is also a very nice and approachable guy. i talked at length with him many years ago at carlisle about the independent suspension i was fabbing for my 33 dodge humpback panel truck. he offered many helpful tips and gave me good advice on how to jig up the control arms, plus directed me to several very helpful books on suspension design and theory. when i ran the completed setup through total up and down travel, his tips paid off, as bump was practically nil, and the camber curve was very good for my application. this design and execution for my front suspension took a little over 3 1/2 years, and although an enjoyable experience, i'm not about to do anything like this again ! i think i lost some of my hair over this !
