Does anyone know of a shop that will install 4.30 rear-end gears in Southern, Indiana around Jasper or a shop around Terre Haute? Most shops that I called won't do the swap, and another shop said that going from 3.27 to 4.30 requires another special tool since the pinion is so big. Thanks for the help.
How about going to Kenny Brown http://www.kennybrown.com/ They look like they are an hour or so away from you, just call them up & ask for a quote.
There is a new shop in the Indy area that is suppose to be pretty promising. go to www.indianaracingscene.com
