Cummins performance parts. I was told they came from haisley machine, can't confirm that. They weren't of too far, some of the angles where the line connects to the transfer tubes were off so getting the nut to start was a *****. Line 6 was about 3/8" off but it wasn't hard to reposition. It was really just time consuming and cramped the tunnel ram didn't help.
I was going to sag havr fun with the lines and that tunnel ram... but you found out the hard way. I really do not think they are worth the money, good luck with your swap.
Looks good man. Did you paint that or have it powder coated?
Glad its coming along
