As Alben78 says , it can be a DIY job but you will need the right tools for for locating the wire tensioners across the cushion backs . I believe it can be a bit tricky . Have a look on websites for how to do first to see if you feel comfortable managing the task . That`s what I did before tackling my 1980 but as the covers the vinyl covers were shabby and foams where so so , I decided to bight the bullet and go for new all leather pads ready made to avoid getting any ugly creases if I didn`t get covers tensioned correctly . Cost me £895 plus VAT three years ago from Claremont Corvette .
