Oh yes mr underhill1975a, Wow,I'd be "hard pressed" to swap those two, but then I've seen some amazing errors in the last 30 yrs. lol whew! Yes, the spring is right where it needs to be, the new foot control lever tab just wont fit far enough into the spring, any lever movement & it jumps right out of the spring, it barely fits into the spring about 1/16 of an inch.
visually comparing the old & new lever SPRING TABS, the new tab is about 1/4 inch shorter than the original. The Hitchcock image didn't show the RS foot control lever or I'd be more specific with the "spring tab" that I keep referring to. it's not the "fork" part or the "spline" part, it's the part that would fit into the spring that helps keep it "centered in the correct place.
I hope this clarifies things a little bit. so....any thoughts on my delimma? any thoughts would help, otherwise, I'm thinkin welding on it is only going to "weaken" the whole lever. I'm tryin to NOT do that. Thanks, in advance, R.Tillery
