I have put a couple thousand miles on my ‘75 WRX powered 914 and I am looking to address a couple of issues. I ran rubber lines from the radiator to engine under the car, think I am going to replace them with stainless tubing. Anyone else do this, looking for some pics and sizing suggestions so I don’t reinvent the wheel.

I also made a stupid mistake of using an eBay civic clutch master cylinder, which on a drive to breakfast is starting to fail. Chinese quality is not too impressive. Anyone have a source for Honda OEM bits?
Thanks

metal helps avoid opening your “easy” to bleed cooling system to the world. ive seen 1-1/4 to 1-3/4 OD tubing. Im still not a fan of running them under the car but without reinventing the wheel, the easiest. i had 1-3/4 on mine i think, worked good and fit in the channel nice. As far as slave cylinder, if you have the part number or year and model a dealership or your auto parts store should be avble to help.
