i'm digging deeper into my newly acquired 71 sportsroof j code 4 speed. has a rusty battery tray- rotted out corner!. are those repo's close? what i've seen from vendor's pics the profile is different. are they the same as used on the early 70's torino . remnants of battery ok sticker. no caution fan sticker nor 429 sticker on air cleaner lid. 47K orig miles
