Hey folks. I would like to convert my 88' PMD21 nissan datsun truck flywheel (TD23 engine) to a single mass, but am having a hard time navigating through Japanese sites. For starters, just wondering if anyone knows if the kit does actually exist. If it doesn't, then i have a great truck for the graveyard. (new DM from Japan is $1500 + shipping to canada) More than i can spend on an 88 ute. Anyone?
