well had little break down past weekend. chain broke and cracked chain case and cover. so was wondering if anyone had extra laying around? thought maybe while apart i change out sprockets on driveshaft to 3.0 pitch. so guess looking for them also along with some kk 162 rails. any help let me know. parts list needed for now- chain case and cover, kk drive sprockets (3.0), and 162 kk rails. thanks dan
