Try Just Suspension or Moog for front end parts, there is a guy on ebay in Texas that sells repo T/A hoods for $700 and he makes them, hood pins other than original Year One has them (I used them on mine look great, also the T/A used rivots instead of screws to mount the hood pin plates to the hood), someone can correct me but I believe the antenna for the T/A is the same as the A-body antenna, but has an extension on the cord, First Place Auto Parts (
www.fpap.com) sells Mopar Authentic repo spoilers, the exhaust is available from Accurate LTD (
www.accurateltd.com) excellent quality and they are in Oregon, if you want new mirrors try BEA Parts (
www.beaparts.com) not sure if they are made in the states or not, Mopar does sell a new 340 block but it's like $1700, so your best bet is of course to find a used block, Mopar sells complete 6 pack kits and I believe the parts are all american made, for the T/A air cleaner contact Ben Snober in Oregon (
www.shakerhood.com) he sells high quality repos and I believe they are made here in the states but not certain, 727 can be bought used and rebuilt, Dash Pad your best bet unfortunately is Ultimate Rides in texas and you can either hunt for rallye gauges or if you want to spend a premium for fully restored gauges RT-Engineering has them in stock I believe for about $3,000 (
www.rt-eng.com). Hope this information helps and if you need more sources just let me know.
