Hey sorry to but in but would you know if there’s any parts that would’ve used on both the 43 and the 45? I’m currently trying to restore a 43 but finding it hard to find anything for them. I want to keep all the original parts but not sure what to do about bearings and chains. Also the drive shaft has been cut off at some stage and thought maybe a 20” mower from a different model could replace it? 
Cheers
