Lower Rad Hose: 1-3/4" In and Out

Our typical V8 F-bodies have a lower rad hose that's 1-3/4" at the pump and 1-1/2" at the rad ( if I've got that right).
With the aluminium Griffen rad I have the lower inlet is 1-3/4".
I've literally been looking for years for one that fits.
Presently, and for the last 25 years, I've used a cobbled together piece made up of two different hoses.
I thought I had found this holy grail by using, of all things, a lower hose from a 55-57 Chev with a V8. While the inlet and outlet are correctly sized, and the overall shape is right, it's about 4" short.
I'd like the avoid the old standby flexible hoses if I can so here I am asking the masses if they've encountered similar.
FTR: The top hose is 1-1/2" at both ends rather than the 1-1/4" at the rad. I found a moulded substitute that fits 99/100. I'd had to look up the application (again) although I know the lower hose is a no go.
Anyone?

That's something I've considered. Thanks for the link and I'm going to price it out.
Considering what I've sunk into just the engine at this point, what's another couple of hundered bucks!

I wonder if these guys are a viable option?
