Other than the Pistons, the injector body itself most likely will need machining to restore Poppet travel. Complete instructions on this are included in the Kit.
If you cannot find a shop to cut your Pistons for $50 to $100, you can send all 8 to me and I can be right in there. BUT I have to have yours on hand. The reason my Pistons are so much $$$, NOBODY ever sends theirs back for cores. I used to offer a core charge but never get any back. SO I had to dive in and have a huge batch made at a good expense, so now I can't afford to offer a core charge. But if you send me yours I can cut you a break on my price on a machined used set vs the ones I have made.
