Installed a MM Manual Clutch cable adjuster kit on my 88 LX 5.0 to replace worn out original unit. The problem is the adjuster does not stay in place. after a few weeks the adjuster has twisted back into the firewall making adjustment required. Its a long slow process, so it does not happen at once but over many weeks of usage. When I installed the adjuster, I used copper anti-sieze on the threads. Maybe lubrication where it was not needed? Any thoughts on this?
