Looking to replace my aluminum rad in my 71 rr with a factory looking aluminum rad with both inlet and outlet on the drivers side like the oem radiator was and a factory shroud can be used on it. My question is im looking for rad hoses for it don’t want to spend $70 for a hose with mopar part numbers on it. Im looking at this lower hose has no spring but lots of good reviews.

The spring is a good idea to prevent collapsing. If your old hose doesn't have one I use one from an automatic sprinkler head although they are a bit more robust than the originals.
 
I read this article and he says not necessary. Can’t find anyone locally whos sells just the spring alone.

I found this article too.
But it's from a book written 50 years ago.

I made mine out of a coat hanger.The coated kind to prevent rust.
Coiled it around a piece of exhaust tubing I had. Works for me.
 
Ordered the gto spring $7 . Ive read people saying newer hoses don’t need them anymore because better designed hoses then 50 years ago. Do newer vehicle have them?
 
I bought my lower hose from Eberg. It did not come with a spring and I installed without spring. 68 Charger with 511

Is it stainless steel as the link above for the Mustang? My original hose had the metal spring that rusted out. I replaced it with that stainless steel one for the Mustang and it’s still going strong.
 
If you use rust inhibitor [ why wouldn't you? ] the coat hanger will not rust.
 
The spring is used for the outside of hydraulic hoses and it is made from stainless. I bought a foot of it and cut it to fit.
 
New oem style radiator is in with bottom hose spring installed. Thanks for the advice!

I'm on the "use a spring" bandwagon as well.
Got there some years ago when I witnessed Fred's lower hose (a new brand name one)
actually collapsing every time I gave the engine a good hard rev when working underhood.

As shown by another already, the factory service manual calls for one and for the price,
they're cheap insurance - so why the heck would you not use one?
