    So this is a bit of a trip for you but might be worth considering...in Southern California, there is a huge Mopar show every April (Soring Fling) and every October (Fall Fling). They have a huge swap meet at both events. You can probably find a lot of the items you need at bargain prices. I always see big sheet metal items for our cars. Every show, I come home with tons of cool finds. It's like Christmas. People are really cool there too.

    Another advantage is the car show itself. You could examine dozens of Challengers and take reference photos of the things you need to aid you in your build. Seeing how things fit together up close can sometimes be way more helpful than a few photos. You might even find one that was converted to a 70, then you get the benefit of talking with the owner to learn more about the small details.

    If I were going to do that , I would just buy a new style Challenger. Plus, I hit pay dirt on a craigslist parts lot that had a bunch of parts that I needed.

    I’ve got a 72;and will change to 70 taillights

    Wonder if I can find a rough 70 tail light panel and just cut out the lights and graft into 72 tail panel it that would be easier route

    it would be cleaner to do the taillight panel.

    A lonnnggg time ago (about 1977), I made the conversion from my '72... bought a new 70 grille, bought a new full tail light panel... cut out the fender side-light areas and welded in same from junk yard fenders (essentially changing my fenders to become 70-71 fenders.

    Took off the Rally front fender side pieces and strobe stripes, welded the holes..   Welded the antenna front fender whole; relocated to correct r/r quarter panel area.  Installed the different wiring harnesses for the lighting.   Repainted accordingly and added the T/A stripes (actually, perfectly painted on using a T/A for dimensions (the sided mirrors are located differently on 70-71 vs 72-74 doors, so the factory decal striping wouldn't match correctly.

    Some items new, some from cars stripping for parts (T/As and AARs).

    I owe it all to my best friend who owns a body shop and is Mopar guy and perfectionist in all his work.

    All this was done simply for SCCA Solo II AX rules, at that time.... later years... they changed the rules whereby I wouldn't have had to do this to the car.... was a nice rust-free 318 '72 Rally... now 340-6 T/A... clone/tribute... and I've continued to race it a lot for AX/HSAX/HPDE events.... won multiple season championships since the late 70's.  Enjoying the car as a '70 T/A in all my campaigns... races and shows.

    Mopar Mitch, Very nice conversion! I thought the steel hood rubber stops in front of the radiator cross bar had to be relocated behind the radiator cross bar for a T/A hood. Does it matter? see picture

    Mitch...does that mean the new motor is in and we are going to play this summer??  my car should be up and running in a few months...how cool would it be to have two 72 challengers converted to 70's on the track at the same time :burnout:

    Rubber stops????  I honestly never knew or considered... nor concerned... my body shop man did the hood alignment, etc.  The fenders are still my original '72, just with modified side lights making them '70-71 style.

    My car is still all apart... slow progress... goal is this August 18-19, 2018 to run at the Joliet, IL Autobahn HSAX event for the club (NORTH SUBURBAN SPORTS CAR CLUB) which I'm now President for 2018... www.nsscc.org (see latest news letter, etc)... part of the MIDWESTERN COUNCIL OF SPORTS CAR CLUBS... www.mcscc.org   It'd be great to have more MOPARS at these HSAX events... Joliet Autobahn is a great "country club" track.  Most of our club's events have recently been held at Blackhawk Farms Raceway (just northwest of Rockford, IL).   This is the only "HSAX competition championship series" in the country... this year only 4-events planned, tentatively.
