Default Shimming front end

How many locations do you need to add shims to if trying to raise the front end to close the uneven gap at the doors?

Where can you buy these shims?

I tried searching threads, but am still a little in the dark.

You will have no luck trying to close the gaps on a `77 with shims or front end adjustments.

The fenders are bonded soild to the cowl so shims won't help unless you are installing a new front end.

You need to make the adjustment with the door hinges. It's a major pain in the A--. Took me about 8 hours just to do one door.

Previous posters are right, no adjustment that way in the area of the doors.

It looks like at some point in the past the core support has been replaced. After removing the doors, I can see some separation at the top near the windshield. This initially lead me to believe I could shim the front up to close this gap.

Not.
The fenders bond via extensions which in turn are bonded/riveted to the cowl and firewall. This fact will allow some flexing. This can be seen in action if you jack up the 'Vette in the center of the frame, under the door. The door to fender cap will grow as you jack up, due to frame sag. Minor (1/4 inch or less) adjustments can be made to the upper door/fender gap by shimming up the radiator support or repositioning the frame extensions.

I knew the extensions were their but have never tried to make the gap less only when bonding on a new front end. If I have a chance to need to try this I sure will as I can see how it could make a small change in the gap and sometimes that is all that is needed.
Thanks for the tip
