Same here. 1st pic looks the best.
For myself, I just want (heh, "just") the lower portion of the 84/85 bumper/airdam with the upper portion of the early 82/83 so it still fits w/ the amber signal/running lights. If you notice, the later bumper doesn't have the raised corners under the signals because the later signals were extended to match the concealed pop-up headlights.
The other thing that I've begun considering, is the lower portion of the MA6x Supra bumper/airdam w/ my upper portion. I think this may require the use of Supra front flares to properly meet up w/ the wrap-around from the airdam. Would look killer tho!!
