Acorn 2200 series sliding window pile weatherstrip

My home has old Acorn 2200 seried sliding windows. I need to replace all the weatherstrips. I have, what i believe to be, a parts list for Acorn 2200 series sliding window parts. The weather strip part number is 340-40120 and the drawing shows a spec of 1/4" base width and 3/16" pile height. Also the roller housing has a part number of 570-22002 and its drawing indicates its 1 5/8 long, 5/8" wide and shows a snap in top that is 13/16 high which uses a 5/8" diam. ball bearing roller with an overall width of 1/2", roller foot print 1/4"wide and 1/4" diam axle.

I was unable to locate either of these on your site. I would probably need 2 or 3 hundred feet of pile weather strip and may be a dozen of the roller assemblies.

Thanks for your help and time. Its greatly appreciated.
