Yes, probably. I hadn't even thought of that, thanks for jogging my brain! The only hitch is that the end of the spring needs to have the last coil bent in and sanded flat. I could calculate how many coils to cut off for a given spring rate, then do the math and make sure there's still enough travel so that it won't run out of space to compress before it bottoms.
But then I don't get any boxes of bright shiny new parts in the mail
I like to keep my stock parts in one piece if I can but if the 29mm springs don't fit this could be the way to go.
