Second that, on my '86 90 the illumination circuit is manually activated, in alternation with the interior light. Took a while to work that one out when I first got in it, brings back memories of initial ownership joy/terror!

Thanks Ross After some considerable research I've got to the same place - basically, the answer (and I'm sure this will be a godsend for anyone else searching for this in years to come) is that yes, the base casings are indeed identical on an early 90 and an RRC, ASIDE FROM the brake caliper mounts. Which basically look like two little 'bunny ears' on the lip at the end of the casing. The second problem you then get into though, is that the hub on the 90 (drum braked) is different to the hub used on the rear axle of a disc-braked RRC. As the 90 hub just has the drive flange bolt holes. Whereas the RRC hub has both holes for the drive flange, and further bolt holes around the outside of the hub, to secure through to the front face of the brake disc. There were 2 reasons I was looking to maintain the original axle: 1) Sake of originality; 2) Planning to strip right down and sandblast anyway, then build out with new parts for effectively a new axle anyway - so why end up with a spare casing and diff in the shed. However, the bigger problem is the hub issue - with new parts being around £300-400 for a hub (each!) it basically reverts a cost-sensible builder back to getting a second hand RRC axle for those parts. Which means why bother fabricating the mounts, when you can just use the RRC axle in the first place. Anyway, thought the write up might interest a few. Took a while to figure that out! And the result is, I absolutely concur, just get a rear RRC disc braked axle. If anyone happens to have a decent one on stock, then do get in touch!

Hi all, attempting a rear drum to brake disc conversion on a 90. Aware that there have been of attempts/demos/suggestions on how to do this, however my plan is to essentially strip the 90's rear axle right back to the casing, then essentially build a Range Rover classic style brake disc assembly out from there, using all of the RRC parts. Is this possible? I suppose the root question is are the axle casings on an early 90 the same as those on the RRC? Also, if the answer is yes, they are the same, then presumably I may have other complications around stub axles sizes etc, or are these all the same too?
