I'm not so sure about papers etc for homolgamation but when we needed some custom made coilovers for the dragster we had a great service from AVO in Northampton
once we fitted em and had a few test runs for datalogging we worked out we needed a different valving and they stripped and rebuilt em to spec while we waited so we could get back out that afternoon
if you need anything custom made you won't go far wrong with them to be honest - give em a shout and see what they can offer ???
