will a 75 duster power brake booster for disc brakes bolt up to a 69 dart. ?

 

Yes, it will bolt up. Are you converting to disc brakes from drum? If so, you need upper and lower control arms, spindels, and proportioning valve from the doner car. Dont forget to replace the rubber brake lines as well.

 

This conversion will work but, it will widen the front wheel base.

 

I did this on my 66 dart and didnt notice any differance in the front end.how much is it supposed to widen the front end and why???
