Being offered is a set of 8 pairs of connecting rod bearings by Michigan, their number R6900C in .020 undersize. Box is also marked 1900SB, a Federal Mogul interchange number. It is my belief that these bearings were never run. They may have been installed as a test fit. Some of the shells may have light scratch marks that should not affect their use, in my opinion. According to my research, these will fit 1953 thru 1955 Dodge Red Ram Hemi in 241 and 270 cubic inch, 1955 Plymouth 241 Poly and 1955 and 1956 Dodge & Plymouth 270 Poly engines. Please do your research as for your application before you buy. They are listed at $30 per pair at one of the websites. My merchandise is located in Canada and will be shipped from North Dakota upon my next border crossing. It takes me about 5 to 6 hours to drive South, drop off parcels, pick up purchases and return home. My next scheduled trips are April 4th, April 25th, May 9th and May 23rd. Illness or weather can also affect these dates. I work hard at making sure my customers are satisfied. Feedback is given once I know that you are happy. Loc: Basement bearings
