Got a deal on a Flux

[josh9mille]

Got tired of breaking e revo axles so i found a flux on craigslist other day. went and looked at it and it was in mint condition, only ran 2 sets of packs through it so i bought it from the guy. offered him 400 and he agreed. Couldnt be happier with this thing, it does need the BP diffs though as this still has the first gen diffs. So do i just call HPI and they will send me diffs? Or do they need to see that i broke a diff first? I do have the original reciept so i dont think that will be an issue.
