Default One piece rear clip alignment

This should probably be in the body and paint section but I think there are only 3 regulars hanging out there....

So here I have a one piece 'vert rear clip that has been bonded in place. All other areas are aligned straight and level. Problem is the door lines not matching the fender crown and deck lid.

This is a view of the drivers side. See how the door lines go one way while the fender and deck go another

Passenger side view when the deck lid is raised to match the door line

The door and fender crown line match nicely but when the deck is raised to match the top of the fender is lost.

Clip is from a reputable manufacturer and otherwise has been correct. Anyone with experience hanging a one piece?

I think I would lower the door to match the deck lid in the latched position with a weatherstrip installed, and then work the fender and door to match. Too late to do much anything else.

I guess what I'm looking for is which component is wrong? I could contour any of the three to match the other two but which one is correct to begin with?

When you say "Too late" you got me thinking about what I could have done different. If I had raised the clip so the deck lid matched the door the fender line would be too high. The option would be shave the fender or build up the door. Either would have created problems of their own.

Something is wrong here......

Who installed the one-piece rear clip? Do the doors otherwise fit well? Have the doors been off the car?

What you are going to need is a blunt object that weighs anything between 5 and 50lbs. Then hit it repeatedly until it lines up... you may have some cracks once you are done but that is expected...

Hi Blain,
I'm NOT a bodyman!!!!
If I had your situation I believe I'd cut the one piece clip apart so you can move the various pieces to make all of it line up with the doors and rear deck lid. I'd then use glass mat and resin to bond the clip back together. It'll sort of be what you would have done if you had a 'built-up' rear clip rather than a one piece.
Regards,
Alan

I'm not seeing a "Ah-Ha" answer here.
Looking for someone to point out something I missed or didn't consider.
You know the one that make you go "Crap, I didn't see that"!

I have a factory door and a clip from a reputable manufacturer. One or the other is incorrect as far as I can believe.

I have made a couple of educated assumptions;

A coup and 'vert door are the same '68 through '80
Quarter fender crown lines are the same '68-'74 (probably '77)
Vanacors builds a good product

Any of these assumptions wrong?

For your purpose the doors are the same as far as their outward shape. There are differences. 68 is enough different to be more or less unusable on any of the other years. Other years have some different treatments for interior and internal improvements. But only one GM parts door has been sold in later years for 69-82 for replacement. The window is different from coupe to convertible.

Take some measurements where you have the problem. Like a reference point to top of door, top of quarter etc. Post them and then we can do the same measurements on cars that line up well. That should isolate the problem pretty quick.

My money is on the rear clip being wrong.

Is the body now back on the frame? Do not attempt any major panel replacements with the body off the frame. They could get away with it on the assembly line because they used jigs and fixtures which held everything precisely in place.

Leave the doors as they are. Leave deck lid in place, but be prepared to wiggle with it. Rehang the rear to align with the doors and decklid.

Alan's idea also has merit.

The Glas-Ra volumes might also help.

BINGO!

From everything I have read, the 68 body was slightly different. Starting in 69 GM used a different company to build body panels. (with different molds)

I get what your saying about body off of frame- I'm going to leave my door gaps tight until it gets back on the frame for final cut. But if you look at the angles of the door compared to the clip there isn't anything the the body could be doing to make this happen.
The body was leveled when bonding the clip. Under the Oak tree now to keep the dust off of the shiny cars!
Not practical to reset the clip. I used about 5 cartridges of Duramix.
Doors are from a '78 so the '68 differences are not an issue. Just some minor bracketry on the inside.

So I think I'm beating a dead horse.
The door will dictate the fender line. So I think my solution will be to build up the fender to meet the deck lid.
I don't have a vert to refer to other then some pics' on the forum. Can any of you vert guys tell me if this angle is correct or should it be flatter?

The masking tape represents the new angle or contour if I fill to the deck lid.
If I build up to the deck the angle will be less and it will appear flat compared to the current crown line. This has been my struggle to keep it that way but if this is wrong for the factory line I'll throw in the towel.....

The dog is really showing his concern.

Make sure the deck lid us adjusted down on the weatherstrip first. Then fit the door to that and then do what you are doing.
