Prior to conversion, it felt like the dash was going to rattle to pieces. This particular truck is a 1995 model with only 20k original miles. We added an air compressor to the 3126 Caterpillar engine and a holding tank on the passenger’s side. The Cabmate air ride is from Link Manufacturing and I believe this model was actually for a Freightliner; they don’t not make a model specifically for the the early Topkick / Kodiak model with the GMT400 bodies.
