We are a pretty good supplier for parts, a few of our KT parts are compatible with HL's. You can always feel free to PM me or email me anytime with any questions on tanks, I am pretty quick most of the time to respond and more than happy to help direct you if I cant help. Taigen has hobby shops all across the US as well that can order parts for you, where are you located? That might be one of your major factors as well.
