A Body Floor pan question

Trying to get info on Ebay panels. Always Leary about EBAY stuff. Lotsa knowledge to tap on here so gave it a shot. Main question im trying to get answered on Ebay is if pans they have go to front seam or is the front a butt weld.

I bought 2 off ebay about 10ish yrs ago, they were kinda generic , and did go to the front seam, which I welded solid all the way across. They took a little more fitting than some people like , but worked out well, just wish I`d have ground/smoothed the under side welding up a little more , figured , ''whose gonna look under it anyway'', at the time.
