Thanks W.I. We are looking at the 73-87 for a trailing arm rear, but....., It only has a 50/50 chance. While a trailing arm is a great suspension choice, it needs to be in the correct platform. Wide chassis, and or high-rail chassis work well for TRA set ups. The goal is to get the arms out wide on the axle, taking the load off of the axle tube and providing a wide suspension base. Narrow, low rail chassis, like the OE 73-87, make this difficult, and with a stock rail, a 4-bar may be a better choice. If we do build a TRA package for the 73-87. it would be based around a new high-rail frame section.
