Made some good progress on the car.. my cousin is almost done with the engine bay getting ready for primer and then my bro @ahcustoms gonna bless my engine bay with a fresh coat of paint.. I had some emotional support from @dumbo_charger and @wildthings03 with the windage tray and milodon oil pan.. all came out perfect thank you guys! And I was able to put the hellcat in the @hotrodmopar K member and it fit perfect and then I was able to bolt up my @TTI stainless ceramic headers.. making some headway! #godfirst #blessed #livermoremuffler #customexhaust #reillymotorsportsalterktion #hellcat #roadrunner

Got a new toy. 86 IROC (ya baby rockin the 80's). I'll install the headers and the Y pipe (I think) and then bring it down for you to bring the pipes to the back (thinking a flowmaster 1 in 2 out, tucked up in the back with a couple of 2.5 tail pipes out the back (not a lot of room to run duals, so figure you can do something for me.(have you order the muffler?) . May also need to borrow your torch skills to add some subframe connectors (weld in). Let's chat, once it's registered I'll swing it by (didn't see any of your vehicles at the Livermore show!!) :(

Did I just read you are considering selling the 66?? What are you asking? (DM is fine). Or I'll come in next week and smack you around (although sometimes there is good reason, but it has to be a real doozie if you are considering selling your dream car, after getting it close to finished?!!?
you making it to GoodGuys at all this weekend?
Hello, I am trying to get a 2" receiver hitch welded onto the frame of my Rockwood trailer. I can buy the hitch online, or from you if you can get it. Do you offer installation? I am using it for a bike rack and possibly a light motorcycle rack. (300lb bike). Thanks!
