Last night I spent about two hours looking for the 1984 Isuzu taillight "guts" for the Isuzu taillights we have on the GVs.
Couldn't find ANY!! Seems most 1984 Isuzus in salvage yards have been scrapped and melted down due to low demand for anything that old.
Things are going to get tough for those of us whose taillight circuit "boards" corrode away.
What then??
Just press the EASY button. Make yer appointment well in advance - they stay very busy.

Sure doesn't look like any of those conversions would work on my GV. And I definitely can't see spending more on a taillight conversion and paint job on a 30 year old coach than I did for the coach itself!!
Are these he same taillights as on your coach?

Nope, ours are horizontally oriented. 1984 Isuzu Impulse with moving the right taillight on an Impulse to the left side on a GV by rotating/turning the light assembly upside down. Same procedure with the left Impulse side to the right GV side.
Problem is the green plastic printed circuit board. It corrodes and crumbles to nothing in our coach's engine compartment.
Forgot to include picture of the lights.
They're the lower ones--just to the right of the FMCA badge and far left.
