I'll preface as saying I don't own a Sandcast. I own an early VIN "K0" model with a wrinkle tank, Recessed key , Louvered side panels and some other sandcast nuances. The reason i came to this forum was to get some tips on restoring the exhaust or purchasing a new one . Also i had found somewhere an English company that repops side covers and airboxes anyone know the name of that company ? Cheers i look forward to conversing with you all
