I think the bosscat chassis is a works, and it goes the other way up with the 'pointing in' saddles on the spur side.
The cougar on the right has cougar 1 front wishbones which are straight, not swept hence the difference in length.
The slipper plates could be for the WASP or the schmacher one as they are roughly the same diameter.
I think the Laser speedos did have different names but I can't remember what (Mini Pro or COMFET pro I think) I know that the front 2 speedos were the ones the racers used to use (In buggys). The relay one does forward and reverse, hence the relay
