new 6.9 specific parts are ONLY sourced from two places... Rusty's and the classic center. There are no after-market parts. Only those two sources can supply new things like gaskets and the like.

For FI parts, and you will need those, most of the CIS parts are identical to any 3.5, 4.5, 3.8 or 5.0 before the days of the EHA and the frequency valves. Compare the ports on the fuel distributor with any used one you acquire and make sure it is plumbed with the same connections. If so, they're interchangeable.

One final word of warning, the things are not cheap and the prices will add up fast. For instance, the metal line that connects the fuel distributor to the UOR is thick in the middle and thin on the ends. That metal line is rubber lined to cut down on fuel pressure waves and is not at all cheap, but that rubber does decay, so you will need it eventually.

Search the site for advice on CIS, you'll find plenty, especially for things like rebuilding and repairing the fuel distributor and the WUR. A well adjusted 6.9 pulls like a passel of scalded cats. It's worth it.
