If they are genuine, it'll be worth your while to take them to an upholstery shop. Especially if they are Momo Speed 2s. (I don't care for seats in a street car that do not recline)
I don't know how much it'll cost but certainly less than the $500-600 Momo seats cost new.
A friend of mine had his '92 Camaro completely redone in grey tweed. 25th Anniversary Edition embroidered on it and a big Chevy bowtie embossed on the headliner. Cost him about $1500. That's headliners, visors , door panels, front and rear seat, part of the dash...etc...
You can pick your fabric and the color and have them embroider the momo logo back on the new headrest cover.
I like grey ultrasuede seating surfaces and that uber-realistic, PETA friendly, Black BMW "leatherique" vinyl balance with white MOMO embroidery.
Seriously, if your upholstery shop can get BMW style leatherique, check it out. It feels more like real leather than the real leather did in my wife's Eclipse.
