hi nigel,i did not touch the factory shims,i made a simple jig that fits acuratly in the new uncruddy top link,then after filling (with weld) old holes,simply drilled new ACURATE holes 10mm in........so,everything should be still factory,but with 10mm added..........i think that is more than ok engineering for my modest BHP.....didnt take pics,too much greif loading on the site here for me!.
also means that original parts are there in case my theory goes pear shaped!!
the jig was just a bit of flat i had kicking around the workshop,10mm seems the max,the top link bows out to the body end so there is a limit to what you can do easily.....im impressed with the turn in tho!!!
