I have had 3 different types, the lightweights, the sprint spec and the endurance spec.
They all look the same on the outside, but the lightweights have a thinner band where the 20 bolts are around the outside, and on both the lightweights and the sprint spec the hub centres are machined out so much that the recessed columns for the hub drive spigots become exposed. I could see that on yours and mine are the same.
On the endurance spec the central hub is fatter so the drive spigot columns remain enclosed by metal. Eggenberger used the endurance ones, where as the UK mainly used initially the lightweights (but they crack like crazy) and then the sprint spec.
I always get Lincoln and Vic mixed up, Lincoln has the white 3dr that I took out to Aus in 95.
The problem with fitting them to a road car is that they were already on the arch limits for the sierra anyway and the hub adapters add another 15mm to each wheel taking them out even further.
The lads that have used them over here have had to open the arches out even more, and/or machine back the hub face of the wheel but that makes the metal between each drive spigot hole very thin. At least the way Lincoln makes the adapters you save 10mm or so by doing away with the bells.
pretty sure they used 1.5 outers which is why I bought a set of 1" but have not had the time yet to rebuild them and try them for fit.
