Finally got around to reinstalling the cylinder and sole plate to my Scott Bonnar lawn king (model 45), started the machine up and the drive shaft to reel chain snapped. Decided to replace all the chains to be safe. Checked my parts list and needed A2984806, A2981385, and A20035, but couldnt find A20035 on the online store or anywhere else for that matter.
Seeing as i have 3 different similar parts lists i checked the other lists and it turns out A2981590 is the same part. so i ordered all 3 from the online store.
In the mean time doing a repaint of the catcher, and will post pics of my machine, in all its glory.
