We could possibly work something out for testing with Dave after Pineapple is finished but I would have to see what I have for 3mm CS. I will be looking forward to seeing pics of your engine on tear down
The 3mm 2pc seals are $1150.25 + GST.....it doesn't get better than that for 2pc ceramic seals

The springs are $140.00 + GST
Total for both sets with springs $2580.50 + 129.03 = $2709.53 plus shipping.
LMK if you want to go ahead and we'll sort out payment and shipping.
Thanks
