KS WIW Highlander seat covers

[jmking9]

I'm selling my 72 blazer and the person buying it does not want the blue plaid highlander seat covers I have for it. They are from SMS. I can't remember what I paid for them, and cant find anything online that shows what they cost. I sent them an email but haven't gotten a response. I'd like to know what they are worth so I can adjust the sale price in a way that's fair for us both. If anyone has recently had a set made, or knows the value of them, please let me know.
If this is not the correct place to post this my apologies and please delete. Thanks
