I already found the Body on a dead Prospector, So how can I get the helmet without doing "For Auld Sang Lyne"?

You can find the helmet at Silver Peak Mine

Ah, the power of Google... Silver Peak Mine, contains a whole nest of cazadors and the legendary cazador so make sure you're packing some significant heat. :gun:

I actually just got the armor + helmet.
The legendary cazador died with 1 hit from my Pushy.
The deathclaws (where the armor is) where no real problem, allmost all 1 hit dead with my Pushy, like 3 deathclaws needed a second hit to remove the one heatlh bar they had left.....

Anyway I don't feel like making a new post so if you guys allow me I'll post my question here.

Where are the vendors that repair this armor? I still dont have the jury rigger perk, but I would like to repair the armor as it needs it badly. (caps are no prob.)

ty

the major at mojave outpost, and raul of course. there are more, i just don't remember them right now

What deathclaw location are you talking about? Thanks.
