I want to replace mine, 81 k10 and i see LMC shows 2 one for the 73-84 and one for the 85-87 my question is this, are they the same dimensions (lenght) and can they be interchangable??? im leanning towards the 84-87 cause i already got the wipers and i cannot mount them on my original 73-84 arms.

Thanks
