[V8] Heater hoses, PT vs ABH

[Scott Simmons]

Finally getting around to order parts and noticed some differences in 
part numbers.

Numbers I found in ETKA:  441 819 371 G, 373K, 373E (3" hose between 
heater pipes and block, passenger side)
Numbers SJM said I needed:  371 C, 373F, 373E

So I went back to ETKA, and I guess the ones that look right are for VIN 
 > 4C, which is 01/08/90 and newer.  I'm getting multiple numbers and 
can't seem to figure out which ones I need.

So I go and dig out of the tool box my old one that I removed.  It's 
373F.  According to ETKA (illustration 113-50), this hose goes between 
the heater core and the heater valve...... but it doesn't.  This one 
went from the block to the valve.

1) What are the differences between the heater hoses on PT and ABH engines?

2) Which hose numbers should I order?!?!?  I want the two that go from 
the engine through the firewall.
