Hello, I'm currently restoring a 66 tanker and I would greatly appreciate any photos fellow NCRS members may have of the factory "grind" in the rear fenderwells/wheelwell openings. The NCRS Technical Information Manual touches on the subject, however, it's somewhat unclear to me. Thank you in advance for any assistance you may provide....I sincerley want this to be historically accurate! Scott

Re: 1963-1966 Tanker
Scott -- can you quote exactly how the 1966 Tech Manual describes the grind ? I notice on your post on the "other" forum that you mention a dimension of 8". Is this the overall length of the grind, or the starting point or the middle ?
I have only the '65 TIM&JG and all it says is: "On both sides, the forward lip of the rear quarter panels have the lip partially ground (shaved) off".
The pic below is of (I believe) an original '66, with one re-paint. Owned by a member in Canada, and delivered originally to a Canadian dealer.
As you can see, the cut is quite crude; the intention is (quote from Aug '64 Chev Service News) "to provide adequate wheel travel clearance for 7.10 to 7.60 tires mounted on P48 Aluminum Knock-off wheels (6" rim width) .... by cutting material away in the wheel openings" (end quote). For the life of me, I cannot see how this factory lip grinding would accomplish anything of the sort. -

we ground the lips completely off front and rear at the top of the wheel opening where the tire would hit and then crack the fiberglass.Comment

Re: 1963-1966 Tanker
Unless larger tires were installed grinding the wheel well lip was not necessary! Why would you do that if it was not necessary or did you install larger tires or wider wheels?

very true but if you lower the car for better high speed handling you will need to grind off the lip or the fronts will grab the fender lip and crack the fender. don't ask how i know that.
you have to remember back in the day most people who bought corvettes used them for what they were performance cars. i had a bud who took a saber saw to the rear fenders of a new corvette so he could install slicks. i ran my on frozen lake race course,on dirt tracks and raced every sunday either at the drag strip or a road course or a auto cross and you needed more rubber on the ground so the fenders got in the way..

Re: 1963-1966 Tanker
Was anything done to the front fendor opening? anything shaved off the top of the opening? I have the correct quarters but also some shaved off at the top of the fender opening.Comment
