Silicon Hose kit from second gen used on first gen
I remember someone posted that they used a second gen hose kit on a first gen. I'm looking for all the non-radiator water lines. I know places like Atkins and MazdaTrix have some of these but these hoses are not cheap. Some of these hose kits are $100 or so and that's a good price point. Plus, the silicon should hold up better.

I just bought the silicone line for the coolant reservoir to the radiator and the radiator to heater line ......
Just measure the diameter of the line and you can buy it by the foot ....

I bought these and they worked great but not sure if they have a 12a heater hosekit but I bet a 2nd gen one would work.

I ended up with all new replacement OEM hoses for my 1982 12A car.
I know not cheap, but I don't think you can beat OEM quality.
And not sure if you are using them already, but the 'wave-seal' style of hose clamp that features a slightly wavy inner ring with radiused edges is really nice. It is a buffer between the actual hose clamp and the hose. Provides a good seal without overtightening and no sharp edges on the rubber.
Edit- The hoses racing beat sells are high quality but just for upper and lower rad. I am weary to trust the no-name aftermarket hose kits in general...

I've used them before and they are equal or better than the one Racing Beat sells and they are about $50.00 less....
Never had a problem with P2M and their aluminum hose clamps are awesome and look awesome ........

Constant Tension Band Clamps (CTBs) aren't as sexy, but there's a reason the OEMs use them. They provide more even clamping around the circumference and can expand and contract to account for temperature variation. They can be a pain in the *** to work with, so get a good pair of CTB pliers like these -->

The most reliable coolant hoses are stock rubber with the stock constant tension clamps that elwood mentioned.
With silicon coolant hoses, you need some sort of hose clamps that hold tension torque over the full temp range. The silicon material is harder than the stock rubber so it also needs more clamping force. The stock constant tension clamps don't work well with silicon hoses in my experience. Worm clamps don't work well long term with any hose in my experience. For silicon hoses, I use an annoyingly expensive constant tension hose clamp. More on this link:

If I could, I'd use stock hoses with stock constant tension clamps.
