LT1 lower rad hose, quick question

It's been 10 years since I swapped my LT1, at the time I pieced together a lower rad hose.
What lower rad hose works for thirdgen rad and LT1?

Thanks!

Re: LT1 lower rad hose, quick question

Check out post #38 in my lt1 swap thread. Can see what I did, it's tough is because pump is 1.25" and rad is 1.5", but this worked very well. https://www.thirdgen.org/forums/ltx-...zz-95-lt1.html

Thanks.. the universal hose was my fix as well.. I was thinking someone had figured out something that fits without the ribs.
The '95 hose won't fit?

Used a 94 Corvette lower hose. Works great, just get that hose clamp tight. And I don't have a ford part on my car either.
