Hey guys, it's been awhile since Ive posted. Over the winter I got a new phone, rooted it, got into techy stuff and have been wasting time with home automation. Now I'm getting back into my car right when I'm not going to have any time because we'll be in the fields soon! :-( oh well, I'll work it in on the side like always. Just like everyone else.
Anyway, if you remember I purchased a whole car to cut the roof off and put it right on my car. Well I screwed the skin up, so I had to buy a new dynacorn unit. I'm still not ready to say it's a bad piece. It is THICKER than stock by several thousandandths and measures spot on to the original (with a tape measure), but I MAY have a couple issues. It seems like it may be a bit short. Some internet searches for "dynacorn roof skin replacement on 2nd gen fbody" will promptly return results of people having similar problems when doing this same project.
I've started locating the roof skin off the stock quarter panels. I'm working forward in a sense. It seems the front may be short by 4-7mm depending on where I measure (.146"-.276"). See pics. I measure off spot weld centers in the donor car skin to the inside edge of the donor roof skin window flange right where it 90°s up to the skin roof surface. I then compare this by locating the tip of my steel rule in the new skin 90° and then measuring to the center of the correspondening spot weld on the inner roof structure. Its an approximation, but I think it's telling. The inner roof structure is welded to the car. I did this measurement for one weld on the PS and one on the DS. DS (2 spot eelds right near each other) was ~7mm and the PS (3 spot eelds right near each other) was ~4mm.
I will NOT be installing the factory window trim on the finished car. I want a flush glass-look. I'm not actually buying flush glass and will just be installing some of that push-in foam/rubber glass perimeter beading around the windows like on the 4th gens and most modern cars. I've seen this on a couple cars at good guys and you'd never know the difference. It looks great and is a fraction of the price of these flush-mount front and rear windows. Even on close inspection it looks like a pricey flush-mount install.
That being said, IF I am off too far, won't the push in seal give me some room for error? If the channel between the front edge of the roof skin and top edge of the windhshield is too wide I think I could get buy by welding in a filler rod contoured to the skin to narrow the gap. Then I'd just push the rubber channel in and its flanges would go onto the windshield a bit and a bit onto the roof skin as they should, and you'd never know the channel was actually a little too wide.
As with all things, I know this is probably easier said than done. I'm probably missing something. Please take a look at the pics and tell me what you think. The side to side ratchet straps definitely help the positioning. The skin was WAY further back before putting them on- maybe by like 3/8". I MAY be able to crank them down a click or two more without worrying about popping the roof skin in. The ratchet strap that runs the length of the car in the center isn't really cranked down or doing anything. When I tried to crank that one the roof structure just bowed and if any of the straps were gonna cause damage it was gonna be that one.
How should I proceed?
