Ken,
I thought the rubber/rope came in 78 but I certainly could be wrong. My 77 has the old aluminum J.

Your carburetor pictures tell me a few things about your carburetor

One is that the 4 bowl plugs, 2 on each bowl have been epoxied over, probably because they leaked at some point. Or at least the 2 top ones that are visible have been epoxied.

In this link to an old thread you can see what the plugs look like. There's an O ring that goes bad and plenty of people have epoxied them with good results.

It also looks like a later carburetor than what came on the 76 PCM's based on where the fuel pump overflow line taps into the carburetor and also the non externally adjustable float bowls that came along in later years.

None of these are bad things by the way. Kinda tells me they did some maintenance and replaced some parts to keep it running good

If you're looking for a rebuild kit for the carburetor, find the list number on the air horn to help you get the right kit. Here's a picture of where to find it

Rob,
The metal line from Skidim works although there may be some slight tweaking needed on the bends.

I was just guessing, I would have thought it was a Commander conversion back in those years. Commander was eventually bought up by PCM. Yes on that first metal line,thats what was on there originally,some where along the way someone cut some off and added the rubber hose.

Looks like a nice start for a great project. Being your Grandparents is icing on the cake.
Check out here the first one or the third one should work even though yours is not a PCM. You can go here to get 10% off too.
