There are approximately 6 Sierras (a couple of Cossies, one is my old Smokestone Sapph K293 FTW still with bumpers rear axle/diff/brakes and front hubs/shafts/subframe/rack) sat in a yard in Mossley/Greenfield near Oldham doing nothing - Think the owner of the yard is the chap with the transit van - if you zoom in on street view onto the van you can get a phone number - Might be worth having a nosey - They were all still there last week when I drove past!
