If it didnt come from Scotts old rubber in OZ then its probably not contoured/curved to fit the screen and will be a terrible fit,send it back!
Its probably quicker and more cost effective to get one from Scotts,as nos ones are rarer than a Dodo,and wont be cheap!!
A good s/h one that doesnt give off black residue,is almost as rare!
And also trying to remove and refit a s/h one is not the easiest of jobs,as it tends to not like being moved about after years in the same place,they often split!
Ive had 2 excellent fitting and looking ones off breakers,and both cracked when with the decker on the workbench, being extra careful trying to remove them!!!
