First off , before any MII install is X measure the frame first to see if its square ! I have see to many nice hot rods dog tracking down the road because they didnt find out if their frame was square . Or they did not use bracing across the rails to keep from warping ...... ect .

Its easier to fix an un-square frame in stock form then it is after all your cross member stuff and extra frame strengthening is done .

I used a TCI MII kit under my 37 ford , and the instructions were very well thought out and easy to follow , I had 1 question though that needed asked , and gave them a call , and they answered it in simple easy to understand answer .
