TH350 to TH400 Conversion, Swap

[dag19]

If I remember correctly I do have the extra holes in the frame for the crossmember. It has been a couple years since I have had to be under there!! I drive it pretty easy when I am goin down the road. When there comes an occasional race I hit it pretty hard but thats about it. Its always just few and far between when I actually drive it. I will have to check into a few shops to get a good feel on what they charge from shortening and balancing drivelines. Good info!
