Clean, Used Porsche 914 Pushrod Tubes - set of 8

For sale is a good used set of 8 Porsche 914 Pushrod Tubes. They have been thoroughly cleaned. 7 of 8 have at least one "ding" -please reference pic 3-4 for close ups of what I consider to be the "worst" one. All have patina and/or surface rust - please reference the last pic for what I consider to be the "worst." None of these defects will affect proper operation as they are straight and true otherwise.Shipping quote is for USPS Retail Ground in the Continental US.
