I'll play along...
My '77 L-82 just about "mostly" stock still except for a brake upgrade to all new calipers with stainless steel inserts,braided steel lines and DOT 5 fluid.The climate up here makes it so and the brakes system has been trouble-free for over seven years now since the install.
Someone in its history swapped out the original interior and put one in from a '78-82 as the gauges are that style and it now has power door locks along with the windows.
Here it is at N.E. Dragway.
