Thumbs up for DMT
At the end of 2019 I bought their 67 convertible seal kit. Turns out barracuda and Dart are different.
I ended up buying a second kit to have enought pieces to get my dart finished.
When I brought the discrepancy to DMTs attention the were glad to document the difference and offered me a replacement set.
I was set already so I declined.
But they did rectify the kit and now offer a second dart only kit!
Very good people to deal with.
