Yes 56 is the same....See link to Assembly Manual:http://www.trifive.com/garage/56 Chevy Assembly Manual/412-4.gif Would be a good idea to have someone to help for sure.....if I still lived in MA, I could be there in short order.Mine's a 56, so it will probably be the same. Any ideas on how to support the hood while I do it? Sounds like a 2 man job at least.
I just changed one about a month ago and did not have to remove the treadle vac.OK, the new vacuum tank came last night and I decided to try this myself. I propped the hood as high as I could and supported the driver's side corner with high density foam and lots of thick blankets. Unbolted the tank, marked the hinge locations on the hood, firewall and hinge then unbolted the hinge and disconnected the tank from the wheel well. Hood isn't going anywhere so I figured I was home free, WRONG! No matter what way I turn the old tank, it won't come out. Do I have to unbolt the tredlevac? Any ideas would be a great help.
Don't remember exactly how I rotated the tank but it did come out, Not easy but it did. Thats why I said make sure you have everything you need within reach once you start. Worst case mark the hinge the same way I described earlier at the hood and unbolt it from the hood to give you a bit more room.Can't see what I'm doing wrong. Are you telling me the tank just slipped out under the treadle vac and power steering lines? Did you remember how you rotated the tank?
