Hello. Looking for some help regarding lever shock oil filling. Have 62 BT7 and have never checked/filled lever shocks. Purchased proper shock oil from Moss and was able to remove fill plugs on the two lever shocks in the front. Proceded to remove rear seats to access rear lever shocks but do not see a fill plug on top as is with the front. Only see a top plate with 6 screws attached. Do these rear lever shocks require oil and if so, where do I fill them? Thanks for any help.
