Mike - Thank you very much! This will help me deal with TRF which uses original part numbers for items not shown in their limited catalog. Wish they would work on making it easier, I have to say sometimes I don't order from them because it is to much trouble to find a part or if they carry it at all. I have wondered why they don't provide a free download for this as this would help them sell parts. Thanks also to the late Randall. I might want to mention to anyone reading this thread the book is not listed in the title as Spare Parts but as SPC so look close it is there. Bruce
