I have a 1984 monte carlo and i need to widen the front end approx. 4" to meet the rear end configuration. i have to use stock chevrolet components. this is for a race application so a little longer on the upper left hand side and a little shorter on the right hand side is what i am looking for.

i have been told a late 60's impalla upper left, nova lowers reversed (left to right and so on) for ball joint geometry<- i dont know this for sure...

any helpful information would be appriciated.
thanks
Darrell
