Re: Front suspension design life?

You are referring to what Packard trademarked as the Safe-T-fleX suspension and it was in use from it's introduction on the 1935 "120" thru the 1942 non-Clipper chassis; it was introduced on the "senior" line in 1937. The new front suspension introduced with the Clipper in 1941 was a rather generic type, similar to what GM developed, and was used thru 1954 and on the V8 non-TL cars though even there parts of it were in common. Safe-T-fleX died in 1942 with the end of the conventionally bodied Packards but a version of it was used on Rolls-Royce postwar, and I believe by one or two other European makes.

Parts between the "junior" and "senior" Safe-T-fleX suspensions are not universally interchangeable. Someone else may know all the details on interchangeable parts but the best source of info is in the parts books.
