There are so many forums these days I really don't know what goes where? I imagine this forum is a good spot for it. If not someone will kick it to where it needs to go. Or they'll delete it and let you know where would be a good spot.
There are some kits at the bottom of this page.
http://www.brenzovich.com/sharps_rifles.htmIf the kit is because of financial concern you can look on gunbroker for ones in rougher shape. I found one a few months back in 45-70 for $450 shipped. It was solid brown besides the receiver. I got the rust off, did away with the pitting and cold blued it. The wood was in good shape. It didn't take long and looks as good as new.
There are decent deals from time to time with decent looking ones around $6-700. The bad looking ones usually have to high of a reserve to fool with but deals come up from time to time.
Good luck
