We have a TKO 600 5-speed in our wagon. Looking for a leather boot to replace the rubber boot that came with this trans kit. At the time it was Keisler, now american powertrain. The trim ring that came with it is nice(fabricated a trans tunnel and inspection plate to which this trim ring fits, nice and flat), but don't much care for the rubber boot. I've scoured the web to determine what the trim ring is for-not much info on american powertrain-and it seems it's for a B,E body mopar with pistol grip? Included pic is what the trim ring looks like, approx 6" x 8" outside dimensions. Does anyone have any ideas for where to find a leather boot other than having a custom one made? Not that it's a problem, but sure would be nice to click-click and have it show up on my doorstep lol. Thanks in advance for your time.
