Mopar performance solid lifters
IDK who is making them, but you can measure the seat height and find some similar. If it were me, I'd call Jim at Racer Brown (after 5 PM eastern) and ask him what he is selling. I forget what lifter he sells. They come in an unmarked box. He can at least steer you in the right direction.
Also, you may be able to regrind the lifters if someone close can do it. If you don't mind shipping, I know for a fact that Kenny at Oregon Cam (in Vancouver Washington) can resurface them for you. It may be quicker and cheaper to have yours resurfaced.
