This is a brand new weld on hardtail rear frame section for 1958 to 1984 Big Twins to convert your titled frame to a rigid custom. This is a high quality frame from V-Twin Mfg. It is brand new. I primered it so it wouldn't flash rust. I have gone a slightly different direction on my Pan/Shovel build so I am offering this up for less than I paid.It is an easy installation.
