DMT Lower steering column charcoal foam seal & nylon retainer for 71-73 A bodies, 71-72 B & 71-73 E bodies and 74 Challengers with manual trans or floor shift automatic. The foam seal is used to keep fumes from going up the steering column. These were installed at the factory but disintegrated after 50 years and are rarely found in the column end. Foam is always gone and probably disentigrated years ago. Retainer is usually broken or missing.

In 1977, at 15, my first car was a 70 Barracuda I bought for $600 from my dad's co-worker at Chrysler Huber Ave Foundry. Tawny gold, 318, hub caps. Before I could "legally" drive it it had headers and a 4bbl. Had a couple other Mopars after this as a young man.
25 years later it was time to get another Mopar. After looking for 2 years I found a 1971 B5 blue Challenger right here in Michigan. 318 and hubcaps again. This time it cost over 10x as much, $6500. Didn't take long to add wheels, new leaf springs, 340 6bbl, etc. A year or two later I decided to completely redo the car. Had it media blasted and painted B5 blue again BUT when I went to put it back together I found there were no good body gaskets sets for Mopars. The gasket making journey began.
In 2004 I first made a kit to redo my Non A/C heater box using a laser engraver/cutter that I had for another side business. I showed the guys on Moparts and quickly had a few orders. I obviously made all the gaskets for my car because I had all the parts for templates. Many parts fit the other E body models so I soon had all the E body gaskets, then more body style, then more heater box kits and the rest is history.
