This hose doesn't look like the one that is on my car now.
Hoping it is NCRS correct.

My (5th Edition) 1970-72 Judging Guide (currently there is a 6th Edition) shows "3946854 LQ" as part number on Base motors with M40 (Turbo Hydra-Matic Automatic Transmission) or C60 (Air Conditioning) [and all 1970 L46 350ci/350hp motors].

So part number looks correct. However, just be aware, NOS items may differ from those used during production. 1970-72 Technical Information Manual and Judging Guide (available from NCRS bookstore) has description of hoses used during production.

Rough "Alligator Skin" texture on production, whereas reproduction often have smooth surface with little or no texture. White lettering appears as solid, filled letters. Reproduction hoses look like they were done with an ink stamp, leaving the center of the letters with little or no paint.

On original hoses, part number and code letters are at the end of the hoses near the radiator, while service replacements and reproductions may have these centered on the hose.

p.s. If you don't have one, the 1970-71 Judging Guide will be very helpful. Radiator hoses are described in Section 21 of Mechanical.

Sorry I missed the upper/lower - would be correct for LOWER hose!

This is a LOWER radiator hose, not an upper hose.

It is correct for your application if your car is also equipped with a copper brass radiator (i.e. THM-400 or AC).

Thank you Gentlemen.
I posted the wrong link to the upper radiator hose. DUH
But the information you've provided will help me in my search.
