I think it's been done, but I wouldn't. Too risky. I think you can probably get by without the oil squirters if you have to, but I'd at least buy a set of os stock starion pistons.

IIRC, I had to shorten the pickup tube on the starion pump when I used it in a d50, but I think the engine positions vs. the front axle are diff between monty and pickup.
