65 Barracuda Fromula S - what to do

Make sure it is definately a formula s. Looks like the factory tach is there in your photo's & that would definately make it one but you never know what a PO did. Fender tag will have a 31 under the AB & a 2 under the C for formula s package. A restored formula s before the economy went south would be worth about $35,000. If a true formula s & your concerned about value I would lean towards keeping her original or doing mods that are easily reversed. Even if you swap engine, trans & rear end which will be cheaper than dealing with the 273,old style 904 & 7 1/4 rear just keep all original parts for future resto. or to sell with car. Looks like she's got lots of potential & unless a previous owner added a dash tach is a true formula s. Good luck with your cuda.
