Series 3 hcpu

Took the back body off my series 3 hcpu. painted chassis and fixed various bits. While i'm there putting on 'proper' body mounts for the rear tub. Old ones were a rubber pad glued to a wooden block which was then glued to the 12 chassis body mounts. New ones are rubber only and about 2 cm thick which rivet to the body. old ones were more like 8 cm thick. If i use the new ones theres no way the body will sit right. So either series 3 hcpu had bigger body rubber mounts (cant find it in the parts catalogue) or the hcpu chassis had longer metal chassis body mounts and my LR is non original. The series 3 hcpu chassis part number is different. Anyone got any idea? ta.

I don’t recall specifically details of body mounts for the HCPU but don’t have the manual to hand. It does feature the HCPU but you’d expect it to specify correct length supports
