Newbie here from Australia. Can not find anything on Google that tells me if a set of 76 DT175 fork springs are vastly different to a 78 set. Part #'s are different but only the first three digits. I have agreed to buy a 1976 gen NOS pair off an eBay seller from overseas as it would appear they are getting very hard to find and they may not even be available from any aftermarket Co's soon. I picked them up for $60US, which is a bargain if they fit. My hope is they are the same but if different I am hoping it is only the length as I can soon increase or decrease the spacer length.
