Speaking of 33/34 Ford 3 W glass body (unknown mfgr at this point) and stock steel doors hinged as stock configuration, any issues or could this be considered an upgrade?
If you are going to do that, I'd buy the doors first and have the body maker use them when he builds your car.....if he'll do that. Things may not line up perfectly if you don't. You also may need to talk to each manufacturer about the garnish moldings you will use on the doors. They aren't inexpensive and you may want to ask about them as well.
Just looking at pics of a "done" car for sale.......from the pics, the doors look to fit fairly well in regards to the gaps. Such a combo of glass and steel doesn't seem all that common.
I would think a nice set of steel doors is rare, and wonder why someone would use them on a glass body? Double check before laying out cash. Some owners don’t really know what they are selling.
I’m guessing you are new at this since you were surprised at the steel hood. That is the standard, and a glass hood is pretty much unheard of. And you called them “side covers “ when the rest of us call them side panels. The terminology and what parts are the usual will become more familiar as you study this stuff. Ask any questions here on the HAMB and we will help you out.
Some people install steel fenders and running boards on glass bodies, fairly common. As Alchemy said, steel hood,side panels, and grille shell are also commonly done. I don't know of any where someone used steel doors, but properly done they should be just fine.........even preferrable. Having bought stuff like this, I wonder whether the doors are originals (probably not) or aftermarket. As I mentioned, buying the garnish moldings may be quite pricey if they are not already with the doors. The only way to check the actual fit is to go look at the car. Also, be aware that when people chop a steel body, they have to decide whether to keep the 3 hinges or just go with 2 hinges. Sometimes the doors will sag a little with the 2 hinge set up. A light fiberglass door may not have that problem.....I don't know. Putting a heavier steel door onto a fiberglass body, I would want the 3 hinges.....but that's up to you. I'd also find out who manufactured the body. If its not a well known brand, it may suffer from cracking and other problems later. Be sure before you $$$$.
