I am working on a 1921 touring. I have in the process of restoring I removed body radiator etc. I have put the body back on as well as all of the sheet metal and everything lined up without any problems as well as the radiato and radiator shell. When I went to fit the hood (original hood) the back fits the wood firewall perfectly but the front curve is not close to matching the curve of the radiator shell. Any sugestions . Am I doing something wrong? Aim perplexed as all of these parts were not changed or damaged while disassembled and hood fit before disassembly.

Be sure the hood upper panel is correct front-to-back, the larger radius is at the firewall.

You only have one upper panel. The fitting of a hood for me is to assemble the complete hood after painting. Then sometimes a slight bit of bending an stray upper panel works. And the hood shelf clips should pull the assembly into position.

As you said, if the fit was OK prior to removing and painting, the fit should be proper unless an un-supported upper panel got sprung during pre-finish paint prep.

I think I would at least turn the hood around and see if it fits better. Looks turned around to me. The fit up of the hood on the cowl end in the picture doesn't look quite right also.

Do you have two right hand sides?

Yes, I believe you have it backwards.

There's something else going on too. The radiator shell should have much more of the filler neck exposed. Either the shell is not sitting down correctly, or the neck/top tank have been modified.

The mismatch at the shell does look like the panels have been reversed, but if that was the case I cannot see how the rear could fit the cowl. It should be way too narrow to do so. If you do not have the hinge rod in place, one side might fit but the hinge line will be well off centre.

Hope this helps.

There were three types of radiators made for Model T's. First was the brass radiator. Later the low radiator was used until 1922, then the high radiator. The low and high looked almost the same, but the high is about 3/4 inch higher than the low radiator. Your car should have the low radiator. It looks as though you might have the shell for a high radiator. This would put the hood out of alignment. Also as stated by other posters you might have the hood panel backward. Do you know whether the shell and hood panels all came from that car before you started your work?
If it were mine, I would install the top and side panels of the hood first. The narrow end of the top would fit the radiator. The side panels would have the lovers facing back toward the back of the car. When you get the panels assembled set the hood in place. The radiator shell should reach all the way down to the position of the bolts which hold the radiator at the bottom and the shell should go all the way down on the neck. If it is high at the neck when the sides are all the way down, you have the wrong shell for that car.

Norman, the shell front panel covers the front panel on the radiator, so the difference must be within the top tank or the filler neck. A high shell on a low radiator would leave the top tank front panel partly exposed.
It would help if we had more photos to work from.
