Wouldn't Diesel Specialists be a little (or a lot) pricey? I would think a transmission shop that handles light and medium duty trucks would be able to swap in a DD clutch. Maybe a driveline shop.
Unfortunately, I don't have any recommendations, so I'm not very helpful.
Diesel Specialists can do it. It just might be pricey.
