So I bought some supposed Cosworth spring and retainers # 28249 from a fellow Evo owner. I received them today and from what I can see, they don't look like the retainers show on Cosworth's website. The springs have no serial numbers and the retainers have no markings either. Has anyone had experience with these? Would like to find out if I got scammed. Thanks

 

Bump. Anyone?

 

They look like cosworth springs but the only ones i find are a different part number. Also they dont have markings on the ones on the website.

Gsc springs dont have markings neither.
