American diesel are good, but last time it seemed to take time,but I think they were making parts for the updated raw water pumps.
I`ve bought cooling system parts from fredwarner1 who sells on ebay. Very responsive, displays commonsense,knows about our 10% tax over 1K, and quick despatch. My coolers,heat exchanger and oil and gearbox he supplied were Seakamp but cheaper than Seakamp`s price list. He also has exhaust angles. He sent some gaskets to our Seattle Hotel last year, they arrived the same day we did. I think Lehman recommends new oil and tranny coolers at 2000 hours, they are not expensive, so best do them too. Search Lehman parts on ebay, that will find him. He responds to messages.
For now think about the cost effectiveness of keeping orders under $1000 AUD, to not incur 10% tax,though that exemption finishes in, I think,July.
Get a quote to check whether, considering postage, it is cheaper to buy the Qld. hx coolers, though I expect they will charge freight on top.
I`ve used US Postal Service as the delivery carrier, competitive, everything has arrived as expected.
