Cooling/heating hoses replace 350 TPI

Good day

I want to replace all the cooling and heating hoses on my 1988 Trans Am GTA TPI 350.

I found the upper and under cooling hose on Rockauto (Brand Continental). Now I am searching the different heating hoses without success. I only found a couple of them but not all that I need.

Can you help me with the part numbers?
1988 PONTIAC FIREBIRD 5.7L 350cid V8 Heizungsschlauch / Rohr | RockAuto

There is a kit on Summitracing but i prefer black hoses. Is there a black kit on the market available?
1988 PONTIAC FIREBIRD Continental Belts and Hoses 5002 Continental Super Elite Blue Hose Kits | Summit Racing

Thank you for an answer.

Re: Cooling/heating hoses replace 350 TPI

These part numbers or descriptions should be what you are looking for seeing as how I have an 88’ GTA as well. The brand is Dayco and the hoses are all black. If you want to view this info in a better format just go to Dayco’s site and look up your car. Also if you need to replace your small oil cooler hoses near the filter just pull the old ones and bring to a parts store and they should be able to get you what you need. Another piece of advice is be patient or have a pro change that small hook shaped heater hose that comes off the heater core…access to that is a nightmare.
