Good clean pair with no visible cracks or defects. Mis-matched numbers but look like a good physical match other than that. 1957 L.H. casting# EDB9431B
R.H casting# B8AE9430A
My limited research shows the R.H. manifold connected with several years. Feel free to correct this info if I got it wrong. They are what they are. $165 plus actual shipping cost for both. Location Bellingham WA
