So I set my motor in yesterday and after that spent 1.5 hrs trying to figure out how to piece together the stupid kit I ordered from LMC. they send a generic install picture with number on it referring to certain pipes however none of my pipes are labeled, now I can obviously figure out the pipes attaching to the manifolds and guess which ones are the tail pipes and I have the system with glass packs, however after that it has been a nightmare trying to figure out the pipe orientation. LMC uses Heartthrob which is 4153gp and lmc has it as 48-5564 if anyone needs part numbers.......has anyone installed this kit ? any pics of it would help.
My 77 is a shortbed if that matters

 

nevermind.......I called Heartthrob exhaust, which is whom makes the exhaust for LMC and I got all of the dimensions and locations of the pipes from them and turns out I had mocked it up correct, I just need to trim the extension pipes as mine is 117 inch wheel base as kit is for 133.........but before I can do any of that I have to put the bed back on so I can line the pipes up with where I want them to exit at the rear quarters

 

Glad to hear the manufacturer was able to help out. Good reference for them.

Post some pics when you get it back together, and maybe some of your work along the way?

 

I have a build thread going, just haven't updated it........will do it in a few days.

 

Thanks for the update. I was looking at these for my truck. Thought of doing Hedman shorty headers with this exhaust so modification would be minimal.

 

I have manifolds on mine so all I have to do is cut extension pipes to length.
