There are about 20 sets of NOS 235 solid lifters on Ebay right now, both the milk can shape and the later design ones that resemble the hydraulics. They're about $125.00 a set which works out close to $10.00 apiece. Not wonderful, price-wise, but they're certainly not hard to get.

Thanks, but those are all for 216-235 up to '54, mine is a '56 engine.
There are a couple sets of hydraulics and a set of "Falcon" mechanicals 55-62, but they're made in China.
I ended up finding the last 12 NOS Sealed Power AT-874
solids that Rockauto had, used a coupon and got them for $11.00 each.
My CS-293 cam is coming from Summit and I've locally sourced Sealed Power springs, pushrods, retainers and seals.
Thanks to everyone for their replies.
