narrowing an 8&3/4" rear

Thru word of mouth i found a local hi performance shop that can narrow my rear for me. Just the housing. I will prob buy my A body axles b4 i bring it to him. Plus i have a 74 A body 7&1/4 rear he can use for measurements. $250, is what he wants plus i provide him with the new perches, and dissassemble and clean the housing before i bring it to him.

A body joe i know your friend can do it cheaper, i wish i still lived in new jersey for that reason, but shipping the axle housing to new jersey and back to abilene texas plus $100 for the work would cost more than just prepping the axle housing, tossing it in the back of my truck, and driving 15 miles away and having it done local.

I am sure if i wanted to fool with it i could narrow it myself. But rather than do it and hope its right sometimes you have to pay the man who knows.

Thank you everybody for your advice.
