Another Seat Cover Question

[rick deford]

Was leather or vinyl used on the 68 Penton seats?. I've read most of the posts on seat covers, but, didn't run across any concerning the type of material used. Also, I have 7 of the 8 original split rivets and washers. Does anyone out there have 1 they will be willing to part with?
Thanks,
Rick

My MGA uses very similar split rivets.  Try mossmotors.com and search PN 325-268.
