I go to google books and do a search on how to build a hot rod chassis. you will get several books listed and some have a preview feature that lets you read a few pages to see if you want to buy the book. read several books, and decide which type system you want. Ford single leaf style, suicide mount, parallel leaf, Quarter eliptical etc ...At the top of this page , click on the eBook, Cboy has posted his book for all to use free, !! Thanks Dewey !!
