    Bondo roof. What to do?

    Thanks for the bout of confidence. I put a scope between the 2 layers and there’s nothing to spectacular to see in there so the pop and pull method will be a learning experience for me. Worst case I use less bondo then the previous version.

    Lack of acceleration

    I have a stock 5.7l 350 with a turbo 400 transmission. I don’t know what my rear gear is but the truck is lacking hard acceleration. Engine revs up and it takes a long time to build any real speed. Is this a transmission gear issue or could it be a rear gear issue? Clearly I am very new to...

    I will take a look at the back of the carb for a vacuum port that’s open. And look into electric chokes thank you.

    Vacuum lines where do they go

    Might be easier to swap out for a new carb? Ports were capped prior to photo and capped again after. Runs and drives fine but needs a little throttle on cold starts to stay running.

    Vacuum lines where do they go

    Can anyone help identify what type of carb I have so I can looking up diagrams?

    Vacuum lines where do they go

    I looked into that position but the ports are drastically different sizes. There is no port on the top that will fit the hose size the choke needs. Also I noticed a vacuum pot on the back of the carb that is wide open.

    1978 jimmy bolt on roll pan

    I was hoping to just sneak it in there. The hinges will stick out over the roll pan I think. I may have to reconsider the roll pan if it effects the tailgate.

    1978 jimmy bolt on roll pan

    Looking for a bolt on roll pan for a 1978 jimmy. I see a weld on option but I would prefer to keep it removable for access. Does anyone know of a product that is a bolt on or am I fabricating one from a weld on myself?
