Combines R62 feed chains who makes the best

do you have 1_2 inch bolts or 3_8 bolts on the slats.have used shoup's chains and was not happy with the life. I got price today from agco on the rear chain cost was $ 930 dollar. had to put on stock order. agco and shoup's were the only one's I could find that had the 1_2 inch bolt's.

Put the updated shaft and chain sprockets on rear feed chain.

I believe loewen also supplies 1_2" bolts, and a choice between American made chain or import chain.
