Default radiator core support

I'm swapping radiators, car is in shop, cam needs replaced and radiator is shot. Car is 71 4 speed, non a/c. I ordered dewitt's model 955, from what I can tell this should fit my car. Paragon has 3 core supports for my year, 71 LT-1 w/o m22, a/c, and auto, 71 bb, and 71 sb, non a/c, lt-1 w/ m22. Can anyone tell me if I need anything besides this radiator to install it? I don't want to buy a $300 core support if it's the same one in the car already, thanks for your help.

DeWitt's Direct Fit radiators will mount in your original support. If you are ordering anything larger than the stock aluminum radiator, you may need a new support to go with it.

In that case wouldnt you need the support described as

71 sb, non a/c, lt-1 w/ m22

I think I already have the correct core support.

https://www.paragoncorvette.com/p-35...350-wo-ac.aspx

My car is a 350, 4 spd, non a/c. Originally had an aluminum radiator. I don't see that the ZR-1 used a unique core support, should be the same as small block base model non a/c.

I might need this:

But I don't see what else is different.

The 955 will mount in that support, as it uses the same pattern pin mount as the 941. The only difference in radiators is the 955 is exactly 2" wider (all added to the driver side) and the upper hose connection is a big curve in and up. Where you might run into problems is getting a shroud to fit over it, in fact, I'm not sure there even was one on the ZR1 cars. The 67-L88 used the 955 and they ran without a shroud because the cars were not intended for street.
Another problem you might have is that upper neck hitting the underside of the hood. I'd probably switch it out to a 941 and make this right. Unless you are trying to counterfeit a ZR-!, there is no reason to go through all this.
