Don't worry, I really appreciate the help with the pictures and all. Looked at the parts book and cross referenced to Timken (BCA/Bower), if it helps anybody: The five bearings (including the pilot) are: W1518Q (mainshaft front, rollers) 1209L (maximum capacity or 6209N/209L for standard capacity, main drive gear) M1206EL and 308L front and rear countershaft and 307L mainshaft rear.
