I have a '79 Targa - front seats are in crappy condition .. any recommendations for new replacement seats (modestly priced)?

 

For new seats, or new to you seats? Cheapest option is going to be to look on ebay for a set in good condition. You can use pretty much any seat up through the 993 years (though if you want a full manual seat, keep to the earlier 911's and 944's.
