[TR] Rings and bearings TR4A. Brand and supplier recommendations?

[Don]

I am finally getting back to my TR4A ,known locally as "The Invisible  
Car", which has been sitting dormant for 22 years.  (The kids have  
grown up and left home)

I've done the head (last year) but feel I should replace the bearings  
and rings before reinstalling it so am looking for recommendations re  
brand names and suppliers. Anyone want to chime in?

The engine currently has the "Big Bore" kit installed with about  
17,000 miles on it but it has been sitting for over 20 years.

TIA
Don
