KeithEM Posted June 22, 2021 Report Share Posted June 22, 2021 Hi The is the first time I've had to post as I always previously found my questions had come up and been answered many times before! Thanks everyone. So I'm just stripping the rear end and have wiggled the O/S trailing arm from the car c/w the two chassis brackets (pivot bolt heads were facing outward unfortunately). I was interested to find each bracket had a fine thread and a coarse thread bolt holding it to the chassis rail. At first I thought one UNC and one UNF but on checking I've got a 3/8 UNF and a M10! So I just thought I'd check they should be 3/8 UNF in case the PO really was raiding the spare bolts bin that day for anything that would fit. I've now got the excitement of seeing what's fitted on the near side! Thanks Keith Quote Link to post Share on other sites
rvwp Posted June 23, 2021 Report Share Posted June 23, 2021 Hi Keith, definitely 3/8 UNF bolts. Rich Quote Link to post Share on other sites

KeithEM Posted June 23, 2021 Author Report Share Posted June 23, 2021 Thanks for the quick replies John & Rich. I’ll have to remember in future there’s more info on the Moss website than in their paper catalog - I’d looked in the later and just found “Bolt” with no size info.

RogerH Posted June 23, 2021 Report Share Posted June 23, 2021 Hi Keith, welcome to the forum. The Moss paper Cat should have al the info in plus a bit more as there are some wry comments here and there. The WebCat is also useful for a quick look up. The bolt numbering system is handy to know The bolt BH606261 which you are interested in B - bolt (S - Screw) H - hex head 6 - UNF (5 - UNC) 0 & 6 - diameter in 1/16" increments (6 - 3/8") 26 - length 1/8"- 3 1/4" 1 - zinc plated ? I'm sure this is in the PaperCat Roger Quote Link to post Share on other sites
ianc Posted June 23, 2021 Report Share Posted June 23, 2021 Correct, Roger - the information is at the start of the General Hardware section, which is at the back of the paper catalogue. In my Issue 17 (quite old now!), it is on page 150. Ian Cornish Quote Link to post Share on other sites
KeithEM Posted June 23, 2021 Author Report Share Posted June 23, 2021 Thanks Roger & Ian. I’ve never got to page 150 before - and there was me thinking it was just a simple part number. If was definitely worth me asking my original question - thanks again. Quote Link to post Share on other sites
RogerH Posted June 23, 2021 Report Share Posted June 23, 2021 Hi keith, all questions and answers are an education. Ask away freely as somebody else has probably got the same question but will not ask. Roger Quote Link to post Share on other sites
AndrewMAshton Posted June 28, 2021 Report Share Posted June 28, 2021 Hello Keith, when you put it all back together remember to put large washers or even better a plate behind the nuts to spread the load, there are some photos on here of my chassis where the nuts pulled through a less than 10 year old chassis due, I suspect, to the point loading on the small washers, cheers, Andrew Quote Link to post Share on other sites
KeithEM Posted June 30, 2021 Author Report Share Posted June 30, 2021 Thanks Andrew. My rails look solid in that area but they’ll get some load spreaders just in case! I’ve also found that my TA mounting brackets are solid and crack free but unfortunately both TAs have small cracks in the “normal” place just forward of the hub mounting flange.
