What were the details of heater hoses for the 1969 model year (Coronet w/A/C)? Were these hoses ribbed or not? I thought they were ribbed, but I know that some reproductions are not ribbed.

Long story short is I am trying to find the best place to buy the most faithful reproductions at a reasonable cost.

on a side note whenever i try to use Year One's website as a tool i find that parts frequently
have errors in their description. in this case they say the 69 A/C cars used one 1/2 and one 5/8 inch hose when both were 5/8. they also don't mention ribbing when in other descriptions they do.... so i need to know what the factory one's looked like
Thanks

They were all ribbed - Not many repops with the correct ribbing. It think Gibson has the closest ribbing.

I think Frank Baldenson has "ribbed" for your pleasure...
Also try Bill Allphin

I was waiting for that.......

most 5/8" hose's I've seen so far has been ribbed

But I also have an original piece around here somewhere off the air cleaner of an AAR cuda and it's a 5/8" hose with grooves.

the better of the repops avail today, (Although are not 100% OE correct) are grooved. The lesser of the ones avail are just plain old smooth hose.
