Ozzy, nice Mach 1 and is that an Eliminator in the background? 
The yellow one is a 1970 XR7 with a 428CJ ram air.
The blue one is a 1970 XR7 convertible 351C 4V
Thank you all
I had a 1969' XR7 vinyl top,back in 1980 w/ a 351W FMX trans and 2.79 rear gears.
Did they upgrade the suspension,etc. for the1970 model/year ?
