First off, yes, I am calling Harwood tomorrow, but thought I would look for some advice here as well...

I just installed a brand new Harwood 4" bolt-on glass hood. The install went well and the hood actually fit very well. I only had to trim the vertical edges where they contact the rubber bumper things. So, I got all the edges lined up and adjusted the hood latch and bumpers in the front so that it closed nicely and the front corners looked pretty good. I confirmed that they were barely touching the front bump stops.

I pull the car in from the somewhat hot sun and let it sit in the garage. I come out an hour later and notice the front corners have lifted. Both front corners of the hood are at least 1/2" higher than the fenders. The area by the latch is still pretty good, but not the corners. Even the rear corners are lifted somewhat.

This photo is a side angle:

This is one front corner and the front edge:

This is the same corner with weight applied to it, so you can see the bumpers aren't an issue:

Here's a rear corner:

Sorry for the long post, but can anybody help me? I will update this after I speak with Harwood tomorrow, but I'm not all that optomistic that they can help...

I've installed two Harwood bolt-ons on my car about a year ago, they both fit and looked good,I too had to trim the vertical lip on the side for the bumpers and clearance the back lip for the windshield wipers,,my car is garaged full time,but has sit many hours in the hot sun at the track with no issues. Now if Harwood could invent a hood that would install its own hoodpins :D

So yours has no issues like this, right? I wonder what happened?

Maybe you have the latch set too tight? I can't imagine that the hood would bend UP off the bumpers but you never know with glass I guess.

I just bought my Harwood 4" Cowl bolt on hood also and am having the EXACT same problem, mainly with the front corners, you apply pressure and it goes down. Did you ever find anything out? thanks

SDuster11,

Did your fit at first, then get worse after it got hot? Mine was perfect initially, then warped or something after it got warm. Unfortunately, it never went back after cooling down. If you want to talk about this further, email me. I may be able to point you in the right direction.

Yeah I just put it on in the garage and tweaked on it for a while and got it pretty damn close but after I got it out in the sun and drove it, it seemed to roll up the edges! What do you know about this? thanks,
Dustin
