[DeTomaso] Steel dist. gears

[Dave Londry]

To finish up my cleveland roller cam install I need one of those nice 
coated-steel gears.
The distributor is MSD small-billet.

I see cheap items from Mallory - not going there.
Also:
Crane 52971  at $72 (jegs)

MSD 85813   at $73 (msd online)

I'm tending toward the MSD gear - just because it's the MSD distributor 
and the description is fine
Increased outer hardened layer thickness (RC 55-60)
Micro polished surface for smooth contact.
Melonite QPQ coated reduces friction and initial wear.
Interstitial carbide concentration improves wear resistance

Any reason to prefer the Crane part??

tks
