c3 Heater hose revisited

[Tony 38901]

I read a past thread (Dec. 2002) re: heater hoses. I am looking to get mine replaced (on a '72 LT-1 w/ AC). Most catalogs have them with or without the GM logo. I have found no other catalogs that have hoses with the other markings as described in the Dec. 2002 thread. So my question is, based on what I found available to me, should I go with or w/o the GM logo?

Heater hoses: May have a GM logo on them.

Many original hoses are seen whith the letters DL or U stamped

Most common designs have 3 or 4 narrow ribs running lengthwise

Air cars have moulded bends at the heater core end

Re: Wanted: vintage photos of c3 heater hoses

I have saved the original heater hoses from my 68. They are indeed rib configuration. I have never seen an original 68 with anything other than the rib style.
