What if the parcel shelf sides are in good condition and don't need attention? Can the cut/join line be lower than Gary's?
I found a picture online (not mine) this morning of a targa panel showing the hoop provision as Barry explained:
My default is to go from the 1/4 light rear curve (the one that's about 3in tall): half way up that and then do an arc that ends up running 15mm or so below the gutter line. You could certainly go lower. I use that height as it allows excellent access and leverage for the PDR rods, and yet keeps the weld fairly short and very well supported.
I always replace the flange on the top of the inner wing: by time it's been shaved right down in the factory, been spot welded and these then drilled out, there's rarely much left that's worth fiddling about with. Better just to take it down to 2mm or so, put a nice wide new flange on as Gary mentions, then shave that down after welding.
Obviously it's an insignificant job to remove the Targa hoop pressing area of the wing top flange, but as I suggested above, template off the original wing flange just to see how similar or not that is to the Targa version.
The long and short of it is that, yes, I'm sure much of the wing will be usable, but if this means great long welds then the attraction is going to wane somewhat.
I take it you have a good pair of Targa 1/4's to hand?
If someone wants to host some pics for me, I'll e-mail some pics of how I tackle this area over.
