? on Brookville frame horns

Has anyone installed brookville frame horns on a stock A frame. I just finished rough welding them on and the radius's do not match. I am thinking about welding along the radius of the original frame back a few inches to build it up then blending them together. What do you all think.

thanks

Did you lay them along side your frame and cut back the extra? They are probably extra long to make sure you have enough material. If you splice in the wrong place, the curves won't line up.
