Welcome to TM 4RNY. Regarding wiper blade upgrades check out this thread. The supplier Peter is a member of TM, MR11MOG and you can order from him via personal message (PM) although you will require around five posts as a new member first.

Definitely stay away from pressure washers with a Morgan BTW.
