Suburban upholstry

[58 Special]

1971 GMC suburban K15
Currently have 69-70 olive bucket seats in front.(very nice 30 year old reupholster job.)
Parchment 71-72 with cloth inserts in second seat. (still nice cover)
Black 71-72 all vinyl in rear(was brown dyed black still very nice)
I would like to purchase all 3 rows of seating with OEM olive all vinyl with proper scrolling. Who can do this. I would like to support venders here. Not looking for cheapest seat covers but want best option, Suggestions please.
