wanted o-rings 4 a 350 ct cylinder 4 a 250r

[85 atc 250 r]

I have ct cylinder that is a 350,I need the o-rings that seal the cylinder to the head,it has a pro cool head if that makes a difference,the o-rings fit in cylinder not the head.this bike is a 89 trx 250r.ct does have the o-rings but they whant almost 15.00 bucks for s/h,I thought that was a little high,considering a padded envelope mail across the U.S. cost around a 1.50..thankx alot..
