Heater System SuperBug

Hey Guys,
I'm still in the process of learning about volkswagens.

I currently have a 75 Super Bug however when i purchased it, it came with an aftermarket exhaust, i am in the process of switching to a factory styled one, however i don't know what parts i need to purchase to install it (so the heater is connected). It didn't come with any hoses however the tinware still has the factory ports.

can anyone please help me out?

Thanks in Advance!!!

just the exhaust side here are a couple of pics to help

Post up some photos of what you have, and we can give you more of an idea of which parts you do need, and which parts you already have
