NOS 1969 - 1970 Corvette Upper (Inlet) Radiator Hose. GM PN 3768956 (Gr. 1.159). DISCONTINUED. Have 3. NO inside spring. 1.5" I.D. Used with 350 w/Sp H/Per (ex HD). Also found in GM Parts Wiki that it was used on 1968 Pass w/CAC HD Rad, H/Per show contact info Pass w/CAC w/427 (ex 3 x 2), 1970 Pass w/454. Has GM stencil striping and PN on each. Stored in a box and kept inside. Never installed or used. Price is Each.

Probably used with other GM vehicle applications. Must investigate your GM PN Hose requirement.

Works with stock intake manifolds, thermostat housings and radiators. May not fit modified cars with non stock parts.

FYI: I used this same hose PN on my 1963 Corvette until summer 2025. I do have an aftermarket thermostat housing that swivels so can align to fit hose bend.
