Upper Radiator Hose for TPI Swap?

Has anybody on here done a 350 TPI swap in their CJ? I'm having a heck of a time finding an upper radiator hose that will fit.
I'm trying to get from the OEM TPI thermostat housing (1-5/16 Hose I.D.) to an aftermarket (built for CJ to 350 conversion) radiator (1-1/2 Hose I.D.).
Does anybody have a part number to share?

I wonder if the hose for a carb’d 350 to that conversion radiator would work. I’ve got a listing of that somewhere.

Randy,

Thanks - anything helps!

BTW, I just found Dayco's site.. They have a "Dimensional Lookup" feature that is offering me some hope. Finger's crossed!

It was a post I did here somewhere. But I can’t find anywhere.

I used a stock 89 4.3 S10 upper radiator hose to my stock CJ8 radiator. Not perfect, but it works.

Thanks, but the conversion radiator has the upper fitting on the driver's side (the opposite of yours).

I think it may work better on yours than mine. The S10 has the upper fitting on the drivers side. I just rotated the hose to passenger on mine.

I don’t have a gear picture, but this is how it sat in the donor truck.

Ah, thanks! I'll definitely have a closer look at that possibility!

Carquest 20827 is what I used on a TBI 350 with a Chevy conversion radiator.

That one does not seem to come up on their (now Advanced) site.
Would you happen to have an application I could look up?

I just found some notes- I have 71659 Dayco listed for an upper hose, and 71904 for a lower. I’m sure some trimming was involved. These were from notes on my phone, so I hope they’re correct.

Sorry to be so late to the thread.
I used a NAPA part number 8835 for the upper. Here is a link with a picture -

LOL. I found your thread a while ago and have already bought and, returned that hose. My motor has a serpentine belt system and a different thermostat housing. As best as I can tell, my motor was pulled from a 1990 Camaro IROC-Z. What did yours come out of?
