Which upper rad hose? ('70 w/460 & Duraspark II)

[MadMike]

Neighbors '70 F250 2WD originally a 360FE, now has 460 appears to be using FE mounts and perches. P.O. installed the 460 and was running points ignition. Radiator appears to be original/original type.

Is Gates 21045 the correct hose to fit a Duraspark II 460 in an Bump??


Originally the upper hose and thermostat were vertical with Gates 21034 and the small cap and points.


Replaced the thermostat housing with 4seasons 84859 horizontal thermostat housing,


This was to clear the Duraspark II cap/rotor upgrade(pertronix flamethrower II coil/pickup replaced points components of the 460 distributor by current owner.)

Picked up Gates 20705

Thinking "460 in a '76 should work". Nope.
Angle is not quite right and, I'm guessing, the FE perches/mounts on the 460 have the engine a few inches higher than should be. This puts a nasty kink in the middle 90° bend.

Going to go snag a Gates 21045 and hopefully this will fit.

I've looked around on a few 385 series into Bump swaps and these details seem to be lacking... or is it my Search-Fu lacking?

Appreciate it if anyone could chime in with part numbers to confirm/deny. Thanks.

I can't help on application, but some hoses came long and could be trimmed.
I've even seen a cut line on some models.

21045 fits. It does need a bit of trimming ~1/2" off at the thermostat housing side allows the hose to fit without jamming against the thermostat housing plug. If no plug the hose wouldn't need to be cut.

Now to the DII wire layout
