no as the 77 isn't as wide as the 71.
No, the chevelle isn't as wide as the impala, you would have to get a rear end from a full sized Pontiac or olds.
No they can not as the fenders and doors are shaped different.
No it will not.
no camino has a straight rear vette has independent rear
A standard Chevelle frame will not fit an El Camino as it was based on the station wagon frame
no
No , the only compatibility for a 1970 Chevelle is a 69-72 Monte Carlo, Chevelle, El Camino... hope that helps...
If you cut the housing down to fit the chevelle it will work but to just take and try to put it under the chevelle it's too long.
Not without some serious modification. Use a rear end out of a '64-'67 GM A body instead. They are stronger and will bolt right in.
Yes
Yes. It is the exact same radio... The El Camino is actually a Chevelle model. It is built on the Chevelle station wagon frame. The entire dashboard is interchangeable between the two.
