Those adjusting screws look exactly like the MOPAR items on Ebay. The same vendor has a similar set with female ends that would work with ball-end pushrods. I'm accumulating the parts to make my own tubular pushrods with 3/8" stainless steel seamless tubing and cutoff ends of MOPAR ball end pushrods pressed into both ends. Total cost for 12 pushrods should be less than $100.00.
