really not that much work. first i just cut the rear quaters off and then ground the quaters about 6" to foot back and then made a shapped template to lay inside the quaters to hold the fiberglas in place whil it set up.
Then i cut the quaters to length and started shaping them. Once that wa done i fitted the tails in. had to make a new mounting bracket to hold them into place.
Than it was onto extending the trunk and fitting that.
i did this car about 6 years ago and the quaters havent cracked yet. i usually keep the trunk closed at car shows 'cause it dosn't look too pretty in there. Will take some pics today and post them.
Later
