What years of seats would fit in a 1954 Vw bug?

I was wondering if the later oval(bug) seats would fit in a 54 bug(oval). I dont see the difference. Are the mounts different. If so couldnt you change them.What years of seats would fit in a 1954 Vw bug?Any Beetle seat thru 1972 should slide right in. 1973's got a new mounting system to prevent them breaking away in a rear end collision.What years of seats would fit in a 1954 Vw bug?the "mounts" are tracks welded to the floorpan. Yours is a lil older than i'm used to however most all beetle stuff interchanges. The seats change shape get taller backs etc. but should "slide" right in
