thanks for the reply & sorry for the delayed response--i have been away from home for a while. i must dsay that i do get the lmc catalog as well and have used it quite a bit on my 1967 c-10. my problem is i have a c-30 that is a little more challenging to find parts for. alot of the items from a c-20 or a k-20 interchange with the c-30 and salvage yards are also a good source. but i would love to find a very good supplier for the c-30. classic industries has the best selection i have found so far. thanks again for the response! keep your eyes open for parts for 9 foot step side bed parts (bedsides & step boards in paticular!)
