Bought headers from this guy if his name is bobby from florida overpayed him they showed up junk bad welding and cracked told me they were nice condition hard to contact him etc etc don't trust him!
I wouldn't even consider buying anything from a man that won't list his phone number, I GUARANTEE YOU there is a reason (none of which would be good) for not listing his phone number.
Are the parts you are considering the ones for the ad that came up? For around a hundred dollars more (according the the ad) you can buy it from someone with a name, don't fool with it man!!
Just my thought on the matter, good luck!
