Wiseco 1990 Piston alternatives?

Hey all

I am currently rebuilding my I/C flatty and have gone with 4.500 rod etc.

I have purchased a 1990p1 piston through a well known kart shop who have messed me around for months and are now not returning emails. Super frustrating

What are my options on sourcing alternative pistons with this rod choice? The 1990 are hard to find and I was wondering if there is an alternative that might be easier to get my hands on?

Thanks
 
because limited flathead has allowed 80 over dyno cams and Weisco aren't going to bother with a part with little to no demand. your gonna need to sleeve that thing and go up on bore. Wish someone would start casting the blocks again the ones out there are on borrowed time. working on a well known Chavis motor this thing is being held together with chewing gum and dental floss. I was half worried I was going to launch the plug skyward last night. threads are literally falling out from wear.
