Hi Vic I Tried calling you today Wednesday 7-2-2014. Didn't get you though. Could you please look up the Kubota S850 Bolt on tiller and see if you can get a screw on cap that fits the tillers oil filler plug. Please also make sure the S850 bolt on tiller is in the Tiller book you were going to sell me? Then tell me what forms of payment you accept? PayPal yes no? International Money Order Yes or No? MasterCard? Let me know ok? Thanks djmc35 - Danny
