I will second the recommendation of Dave at Tritrophy on Ebay for parts, I have got parts from him for my 390 Auto on and off over the passed few years and he has always been reliable and his prices are good.
The only place I have found that can supply the correct oil for the Autos is Imperial Oil

[email protected]The manual says to use Esso Univis J-58. I have been using Univis J-26 for year, but it is quite an expensive oil. The last time I bought some, back in 2015 I think it cost $500 for a 20L drum delivered to SA.
