Best place to buy Suburban seat covers

[FLYNAVY30]

Hey guys, what's the best place to purchase new seat covers for my '72 Suburban? I've only got two rows of seats with the back row being a "full width bench" but its still not as wide as the front seat and has the ash-tray arm rest on the driver side. I know Brothers and LMC sells various options but its hard to tell what will fit the back seat.

Additionally, I'd really like to find reproductions of the plaid seat covers if anyone knows of a company that makes them. If not, I may just go with the houndstooth.

Thanks for the help,
Greg
