exactly what I needed, thank you! so it looks like they sold me the thin inner seal(s) which I am going to assume are correct for the 7&1/4 and the thicker seal(s) which look correct for an 8&3/4. OK I will either take em back or save em for the unfinished 8&3/4. thank you again brother
the 7.25 axle retainer is 4 bolts, the 8.75 is 5 so that one's a quick visual ID. obviously the flange to backing plate is also 4 bolts and is also much smaller diameter.
with a note: the 8.25 is also 4 bolt flange/retainer, but again, it's noticeably larger diameter.
