Hydroboost question

Does anyone know what parts I should get from an early-80s C30 diesel hydroboost system to bolt it onto my '79 Heavy Half? I'm 200 miles from home, and the junkyard here has 4 of them in stock. Sure would like to have one follow me home!

Re: Hydroboost question

Everything! Won't need the steering box but everything else will make it easier. I would even consider the brake pedal itself to keep it a complete system. I've done it a few times.

Re: Hydroboost question

hydroboost, return line tube, brake pedal, and master cylinder if its cheap enough (new ones are pretty cheap). I would personally just buy new pressure hoses from rockauto.

Thanks for the feedback. I'll be back at the yard in the morning to take everything between the driver's seat and the radiator.

Re: Hydroboost question

yeah the pin on the brake pedal is different going from hydroboost to vaccum. ive switched from hydro to a vacuum booster a few times, the first time i found the hydroboost pin on the brake pedal was bigger so i just ground it down a bit
