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.
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 it will not.
no
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.
If it's a similar vintage and bodystyle, yes
Yes. It should bolt right in.
no, because the camaro came with leaf springs.
Not without some serious modification. Chevelles had a coil spring rear suspension while the S-10 uses leaf springs. While I haven't measured, I'm pretty sure the Chevelle rear end is also wider than an S-10 rear end. Now, you COULD change the spring mounts and narrow the Chevelle rear end to fit, but there are alternatives that would be MUCH easier to use in an S-10.
No, the 67's isn't a wide enough radiator for the 69 impala.
Not without a LOT of modification. You need to get a rear end out of a '68-'72 GM A body for a direct bolt in. Anything else will require modification to properly fit.
No, this would not be a direct bolt in.
Yes. 91-96 impala, roadmaster, caprice, and fleetwood rear end are all the same and will fit with no modifications.
