That'a great project you are staring. The Ricko RS200's are a good base to start.
Regarding the wheels, the ones you have posted in the picture look really nice. Two details however which I think you should consider to get an accurate model.
The wheels in the photo are the tarmac split rims - I don't think these were used at all in the RAC 1986.
Additionally, these have 5 stud while on the RS200 the hub only has 4 studs.
Good luck with your project and please don't hesitate to post how you're getting on.
