I'm in the process of putting my top-end back together and have made it to the fun experience of running all the various hoses and vacuum lines. I have replaced the vast majority with new but I have come to a question. In particular, part number: 00004320494 This is number #34 & #35 in the below PET. It connects the control box to the vacuum limiter and also the control box to the throttle body. I have quite a few different hoses that would work but when I finally was able to find a picture of the hose, it looks to be reinforced...similar to brake booster to plenum hose. I'm guessing to prevent the hose from collapsing. So to my obvious question, should I get the appropriate part # or would a different vacuum hose do the trick? It is a special order item, I believe so I'd rather not continue to delay my progress.

Well, just went ahead and ordered the hose. Hopefully it arrives quickly.

Wise move. Those two vac lines are much more stout than the silicon ones (#30 - 33). and I'd be worried of them collapsing. Here is a shot from my 78 when I did the top end refresh.
