John, Top of the top seat across is around 50 1/2" and the middle section of Top I measure around 51" Bottom Section looks to be around 52" across. Bottom section fits very tight between the arm rests. Post us a larger picture of your windshield pillar section. Bob
Usually!:grin: I do my best to post correct information. I'll look it up in my manuals or head out to the garage and take a look before I post an answer. Been playing with my 66's since I was 15.... that was almost 40 years ago!
