I had them from ebay off a bloke who give up trying to fit them to be fair they were a terrible fit I've cut and shortened the front one by approx 30mm and I gave up trying to fit the fibreglass rear so I cut the valence off It and mounted It on the std Ford bumper and blended It In...
Its been a pain In the arse but worth It tho I think...I'll put some build pictures up when I get home from work

If the car has to be kept on the road due to time constraints I would go for the collection bumpers as they are ford Items and bolt straight on I think any fibreglass bumpers would be a pain to fit..
