Chassis and suspension Reference

[Lefturns75]

For you guys that just have to have it period correct, I dug out a blueprint of a Chevelle chassis I purchased new from Steve Smith Autosports in 1971.  I understood at the time the print was done by Frank Deiny of Speedway Engineering in CA.  The Chassis shown is a Chevelle Convertible or El Camino.  I have the long trailing arm sheet also if I ever find it.  There are also some pics from a 1972 Stock Car Products Catalog.  Maybe this will help some of you.
