They haven't made a 36 in a few years now so resale sites are your best bet. They had a few 39's but they were from a few seasons ago and pop up in the SAS. Same thing....try resale sites or you may find the 39 thru customer service. Now they just make the 25 and regular size which is 31?.....it doesn't have a number but some people assign one.They are discontinued completely?
