I tried to paste a link but that didn't work right.Anyway if you go on Tractorhouse and sort for JD corn headsThen for the number of rows, enter 8 for the minimum and the maximumThen lastly enter "Calmer" in the Keywork box and hit SearchKC Nielsen at Harcourt supposedly has a 608c with Calmer rolls coming in.https://www.tractorhouse.com/listing/for-sale/251096839/john-deere-608c-row-crop-headers-harvesters
