CL find... 68 GTS

I went and checked out the green GTS today. It's a real mess, I'm pretty positive that it is not the original motor or trans. Motor is wrong color with blue factory paint not red, also has later model exhaust manifolds. Transmission bell housing is windowed in the 12 o'clock position not sure how that could of happened but not good. Inner fender is rusted out where the battery mounts with a steel plate tack welded in it's place. Need anymore information let me know, price is $5,500.00 I didn't even bother making an offer.
