Hey gents. I've a '53 2.5Ton flatbed truck. I have the original unit but have found it impossible to find a rebuild kit. I've seen posts dating back to '07-'10 of rebuilds but nothing since. Are kits available or where should I go to purchase a rebuilt unit? I've found NAPA & Advance Auto have a hydrovac for up to a 3900 & base models. Best I can research, my 2.5 ton is in the 6000 series. Are they inter-changeable? Thank you for your help fellas.
