Supplier Information Needed

[39er]

Hope you can help, I’m trying to contact Patrick’s about getting pistons and rings for a 59a flathead but don’t seem to be able to contact them either by phone or email.
I am thinking that they are no longer trading, can someone please confirm and if this is the case recommend another supplier that will have the parts (.060th over cast piston 3 3/16 x 3 ¾ and rings) and are good to deal with.
Since I’m in New Zealand your advice would be greatly appreciated.
Thanks
