Dave good to meet you,glad were both happy.......

click on the link,and they are the 7th item down, "ACORN TO BALL SEAT ADAPTERS"

i bought my 1st set from them,they are good folks, it was easier to order when I called on the phone, they were in Missouri in my mailbox in 2days. and a word of advise, order a few extra, $1.00 each throw them in the glove box!.. thnx
