As some of you may already know, my '70 Challenger Convertible is by-no-means stock, and I'm not trying to change that. The prior owner's resto-mod "restoration" includes many non-'70 original parts, and aftermarket/performance stuff. So I don't mind doing what I'm planning to do regarding the A-Pillar interior trim. I wanted to replace both sides because the plastic had cracked at the screw hole at the lower end of the pieces. Several years ago, I purchased original mint condition '70-'74 hard-top pieces because convertible pieces were very hard to come by, or were too costly. Back then, I had read somewhere that the top could be cut off for convertible applications (I recently read that the same thing was done at the factory). The only way I was able to get the trim off my A-pillars was to break it off in many pieces because it was "fused" to the windshield's urethane adhesive. When I placed one of the hard-top pieces on the A-Pillar, I noticed that the lower screw hole was in a different location (higher up). I was crazed and perplexed until I started doing some research here and elsewhere. I now understand that there were two versions of the A-Pillar trim; one which was used in the 1970-71 cars, and another which was used in 1972-74 cars. I believe the only differences were in the location of the screw holes and possibly the hardness of the plastic (1970-71 being harder than the later years). I'm going ahead with using the HT pieces I have since they're in such nice condition. I plan on drilling a new screw mount hole into the A-Pillars, and cutting the tops off the trim just below the top screw hole. Any comments or suggestions on my plan and/or what tool/method would be best to do the cutting will be greatly appreciated. My other concern is whether or not I'll be able to get the drill where I need to in order to drill out the new hole (the windshield is still in place, and I'd rather not have to take it out and put it back in just for this). Pictures are of the two passenger side trim pieces. I lined up the Pentastar and part numbers to show the screw hole location differences. Interestingly, the part #s are the same. Thanks.
