For pricing, best place is to look at gunbroker at completed sales for pricing estimates. Then figure in shipping and FFL fee vs local sales tax. Might not find any for unusual configurations of 24's tho.

For general info, either here or there was a website for Savage 24.. yeah, still there. If nobody here can answer your question, www.savage24.com quite likely can.
