I think a 50 or 51 seat would work but I was hoping there was a newer vehicle that had the same or close to the same bolt pattern. Thank you for your reply
Would this help? https://nwct.craigslist.org/pts/d/goshen-1949-ford-four-door-body-and/7551875236.html And if that doesn't help you could always fabricate a pair of steel adapters to get the bolts to line up. Your frame has nuts welded to the underside that must be used to mount your seat. I had to move my seats back 4 inches even though the seat came from a shoebox. Scroll down to see what I did here to make it work. https://49fordcoupe.smugmug.com/The-Interior/i-6fK4xdG
You might call Roger or Lynne at 620.680.0449 or 620.680.0375..they have some shoeboxes that are being parted out. That's where I got my seats..in Kansas
Don't know where you're at but these are eastern Iowa. https://m.facebook.com/marketplace/item/2688961171235617/
