I can't track down a part number for the coarse threaded brass chassis inserts for the rear undertray torx fixings (item 12 in the link). The usual problem; the insets unscrew and wear rather than the torx stud. Do I need to track down similar size generic M6 rivnuts ? If so recommendations welcome !

Alternatively not sure if the "M8 blind rivet nut flat headed" part no 41132291403 and hex bolt with washer (07119915082) used to attach the floor to the chassis will work. (Items 5 & 12)

Re: Undertray fixings
Many thanks Ivor,
A set of the correct sized "threaded plugs" have been ordered from BMW Germany @ £7.50. The respective Torx screws are no longer available from BMW but generic stainless studs and washers are widely available.
Cheers

Re: Undertray fixings
After 3 months of Z1 body fixing parts being on BMW Germany back order I have finally got around to putting the car back together.
The Z1 workshop manual wants you to insert repair helicoils into the fibreglass before screwing in the brass threaded plugs. No need, BMW have increased the external diameter of the plugs by 3 mm which should be sufficient when screwed and cemented into place. I used JB weld and let it cure for 24 hours. New black stainless steel hex cap screws and washers with low tack thread lock complete the task
