Hey Jerry
I'm in Revere Ma, if you want a good shop that won't stiff ya, I suggest Wakefield Auto Clinic. It's run by a guy named Mark Riley,he runs it with his 2 brothers and he has worked on 4 of my Mustangs.I just picked up a 2005 GT Premium,so I won't be by there for a while,but they do it all there, headers,superchargers,everything! They also race,so they have some cool stuff around,tell em Joe P. sent ya! LOL
If you are looking for just a place with a bunch of parts, there is one in Southern NH that I found on ebay, I was going to order some equal length headers for my car from them,but the price was outrageous.message me if interested and I will dig up his email address. |
