Here is the fender I ended up using. Thanks LCS!
As you can see the curve of the fender is close.
First order of business, weld up the holes, since this is a front fender...
Then take some thick washers and weld them to the edge of the fender where the TH tabs would be...
And here it is after grinding.
Still have to strip all the paint off and do the bodywork. I am happy with how this looks as it is very close to the original, and as an added benefit, the steel on the DB fender is thicker than the TH fender. Should last longer.
