the DT guy Posted February 11, 2022 Share Posted February 11, 2022 i will have to double check but they are either 1" UNS or 1 1/4" UNS as i had to make new nuts when i did the rear end on my 980 Quote Link to comment Share on other sites More sharing options...

Dave Posted February 17, 2022 Author Share Posted February 17, 2022 Thanks for all your help. ive.heard of unc and unf but not uns Sod’s law says if I’ve got spares I won’t need them but if I haven’t, I will. Does anyone know where I can buy 4 of them? is Dennis Roberts still about? Quote Link to comment Share on other sites More sharing options...
the DT guy Posted February 18, 2022 Share Posted February 18, 2022 Dennis is still fit and healthy but i know he hasn't got any nos front or rear spring U bolts as i had his last set for my 980, i'd of thought if need be you can split the nuts and re use the u bolts with out to much trouble?

Dave Posted February 18, 2022 Author Share Posted February 18, 2022 I was hoping to save the actual u bolts by sacrificing the nuts. I won’t be doing the job for a week or two, I,ll see what I can find Quote Link to comment Share on other sites More sharing options...
