Pretty sure I participated in a discussion about replacing heater hoses and valve with 1997+ hoses before. Searched a while and could not find the thread with part numbers in it.
In the Continental selections, left hand drive, the descriptions are kind of lacking. Actually, it doesn't seem like there is a standardized description convention for these parts across brands. Are these the correct two I need for a 1996 XJ 242 I6? "CONTINENTAL63995 Molded; Re-use OEM Quick Connects Heater To Pipe-2; w/ Left Hand Drive"
"CONTINENTAL63996 Molded Heater To Pipe-1; w/ Left Hand Drive"
I tend to order Continental, mainly because they used to be the Goodyear branded products. If they are made identical to the less expensive products, would like to hear about that too.

Thanks in advance!
Pretty sure all you need is about four feet each of 3/4” and 5/8” heater hose.
I’ll double check that tomorrow when it’s light out, but someone else will probably confirm/correct that before then.
If you look at the Dayco parts, the description is much clearer. Those Continental parts look the same, so I'm going with "Yes" as the answer to your question. If you click on the Info for those Dayco parts, you'll also see that ElMartillo is correct in that regular ol' heater hose can be used just fine; no need for the OEM-style molded hoses.
I'll go against the grain a bit and suggest that you spend the extra $10, get two 5/8 barb - 3/4 barb adapters, and plumb it up the "correct" way, with the coolant entering the bottom of the heater core and exiting from the top. I know Chrysler flipped the way the heater core is plumbed in 97, but just because it's "good enough" doesn't mean it's right. Consider for a moment where an air pocket would get trapped and you'll realize you'd have to put your XJ on its roof to bleed it out. I suspect some of the issues people have with crappy heat in 97+ models can be at least partially attributed to this. The heater core will flow perfectly fine with a giant air pocket taking up almost half of the heater core surface...

That's more the solution I was looking for. Kind of fuzzy on the correct way. Does 3/4" (larger) hose go to the bottom port of the heater core with a 3/4" to 5/8" barb? I can get the fittings local I think.
Yep, you got it... The 3/4" hose leaving the thermostat housing connects to the lower heater core tube after downsizing the hose to 5/8" with the adapter. Likewise, the 3/4" outlet tube on top of the heater core connects to the 5/8" tube going down to the water pump after going thru a second adapter. Dorman 47080 works well.

Guess I need a short piece of hose to attach from core to adapter too?
I can't say for certain that the OEM hoses will be long enough, but you may be able to install 97+ OEM hoses as Chrysler intended, cut them both at the same time with a pair of scissors and flip the hoses by inserting those adapters; no additional hose required.

Which ever way you do it the best part is when you get to throw the HCV in the garbage. For those with a RENIX even better ... more stuff to throw out.
