dr side left side bucket seat tracks

[realn96]

I have a dr side seat track that came off a 73 ebody. I believe they changed the seat tracks back in 72 or 73 to this style tracks. The outer is the same as70-74 but the inner doesn't lock like the 70-71..Once installed no one will know ,for you must be original guys out there. Anyway its been cleaned, glass beaded, epoxy primed , and painted and greased the roller bearing and tracks .This is a bolt in done deal..$150 plus shipping from NY 11727
I will be going to spring Carlisle this month on the 20th if someone wants to save on shipping I can meet them there?
