Yeah, was going to say, should be no problem finding a new lower spring. As for the top spring, looks like that would be plenty easy to make. Plenty of instructions on line on how to do something like that, and some of them are even worthwhile. Basically, get proper steel, shape it, temper it. Not made any springs myself, but know a number of people who have, and that's basically how they do it. Once in awhile they get a spring that breaks, but just make another, no biggie.
