hi,has anyone ever changed a c-s in a 69 b body,does it bolt in or is it welded too,is it tough,my car has a 44 in it now,the last guy butchard it up,would like to install a new 26 inch c-s,thanksin advance

Core Support is welded..

yes but has anyone ever changed one,was it tough

I changed both side plates on my Coronet, (Was 22" now 26") it depends on your abilities, it's not overly hard but you need to be able to cut, measure, weld & finish..Did mine in about four hours, if I didn't tell you it's been done you wouldn't be able to tell unless you know how to read the 68 fendertag...

thanks for the info
