Alum radiator neck source?

[rhinoone]

I'm installing a custom radiator, and the lower neck needs a 90 degree bend to avoid some other parts. Can't find anyone local, including radiator and muffler shops that sell alum radiator neck with a 1 3/8" OD.

Anyone know of an internet source?

ive used some aluminum tubing from a company called velocity air for my custom radiator in my s14...worked pretty well i think.
