tommi Posted July 3, 2022 Share Posted July 3, 2022 Hi all, I wonder if any knowledgeable forum members can help me identify the size / thread of a bolt… 1978 Series 3; the bolt that fastens to MUC1324, circled in the attached diagram. I understand that MUC1324 has been superseded by AHR710300 which is M8, but I’d like to know what the original thread is. Many thanks!

western Posted July 3, 2022 Share Posted July 3, 2022 The subject bolt is M8 as denoted by the 08 in its part number, so M8 nut plate is correct. https://www.lrseries.com/index.php?route=product/search&search=SH108161L Quote Link to comment Share on other sites More sharing options...
tommi Posted July 4, 2022 Author Share Posted July 4, 2022 Thanks Western - I hadn’t realised the 08 reflected the thread. Mine are definitely not M8 however… above diagram is from the SIII parts book. I’d like to put a longer bolt in, but unsure as to the thread! 1/2” bolt head.

western Posted July 4, 2022 Share Posted July 4, 2022 Might be in the Series 2 parts book if you can find one. Quote Link to comment Share on other sites More sharing options...
Retroanaconda Posted July 4, 2022 Share Posted July 4, 2022 Likely to be 5/16” UNF I’d have thought? Most of the body fixings were either that or 1/4” pre-metrication in 1980 when they went to M8 and M6. 1 Quote Link to comment Share on other sites More sharing options...
