Main52, here's a couple more pics showing the area on frame where spring towers would need to be trimed.

Pic 1 shows the curve in a stock frame

Pic 2 shows the same area with a straight edge (like the spring tower). You would have to put it in place and scribe the tower and trim to fit frame.

Hope this helps, and if you need more info let me know...Jim
