Passenger Side OEM Radiator Hoses

Guys,

1966 C-10
5.3L LM7 Vortec (LS)
4L60e

Passenger Side Radiator inlet/outlet 1-1/4 & 1-1/2" dia

Curious on what any of you guys are using for radiator hoses both upper and lower. (Part Number/Brand) I think the lower hose can be just a normal '2004 Silverado' lower radiator hose that is trimmed a bit. The upper is were I'm at a loss. What is everyone else using when you have a PASSENGER SIDE upper radiator inlet?

I figured with the width differences not being outrageous..... someone/anyone with an LS swap radiator (griffin, entropy etc) will have some input hopefully as to an OEM looking hose (no corrugated flex) that looked/worked good for them.

99% sure those are the hoses I used ^

I am sure I used the stock lower from the donor truck and just walked around the back of the parts store until I found the right upper.

Re: Passenger Side OEM Radiator Hoses

What kind of radiator are you guys running in those pictures? I am running an eBay in mine and the inlet/outlet are in completely different locations. So these hoses won't work in my case. Just curious what other options are out there. Thanks and sorry for the partial thread jack.

Re: Passenger Side OEM Radiator Hoses

Just got my radiator in also... no chance these will work on a 60-66 C10
(Well the top one might work)

Any other ideas guys?

Right now I'm thinking 87 Buick Regal Lower and trimmed (remove the 90*) 97 Firebird Upper Both are correct diameters
Lower Upper (-90*)

Re: Passenger Side OEM Radiator Hoses

That is exactly how mine looked. That is why I bought a straight thermostat housing. I am going to figure out a way to run hoses to what I have. If you find something to fit your setup, do post it up.

Re: Passenger Side OEM Radiator Hoses

Can the lower outlet be removed from the housing? If so, can you modify it to turn it 90 degrees? I had to do this with my upper.
