I have a 77 Camaro donor car. Will the power disc brake setup work on my 71 El Camino?

It is NOT a direct bolt in. The 77 camaro swap falls into the "tall spindle" conversion. Do a search of this forum or check the disc brake archive for information on specifics. There are a couple of ways to do this & differing opinions on the desireability. Bottom line is it IS doable.

you can do anything ... if you throw enough money at it !!.. your looking at replacing upper control arms lower ball joints & tie rod ends... like the post before this one said do search on tall spindle swap... also do it fast .. theres a group purchase from global west being setup now ... they have all the parts you need ..
