TB vacuum hose diameters
Is there a list of all the various vacuum connection diameters present on the intake of an '84 S model? I would like to buy all the necessary vacuum plugs and replacement hoses ahead of time so I can replace ALL the lines in one shot, car is my DD so I can't afford much downtime. Also looking for diameter of boot connecting TB to intake distributor (the large rubber one) and the diameter of the 8 boots on the spider. Trying to get some silicone equivalents. I can post pictures if necessary for proper identification.
Also need diameter of coolant system bleeder hose which goes from top of water bridge to coolant tank.

I am not certain what all you will need for an 84s, but a good start would probably include plenty of 3.5mm and some 10mm.
I was in the same situation as you (DD). Worked fine to replace them in bunches instead of all at once (still have some to do actually). It takes more time overall, but you can drive it in the meantime.

Did you use rubber vacuum lines + plastic T fittings? I would like to go for silicone all around, but there is sooo much more work to be done on other parts of the car, I'd rather save the money for shocks, steering rack, etc. and use rubber instead. I will get 8 intake boots in silicone if I can find them locally though.

To late for you, but maybe it will help someone else. It took me:
10' x3.5mm
8' x 5/32"
5' x 10 mm
A number of my larger lines (the ones you see directly from the top) were in good condition, so I am not certain the lengths it would have taken for those. The 10 mm I used actually went for the lines to the carbon canister.
The 3.5mm fit nice and tightly for the smallest lines, and the 5/32 fit well on the lines just slightly larger.
I reused the plastic t's - twisting/tearing at the old lines with a needlenose worked well to remove them without damaging the plastic
