Another v8 ?

[50bomb]

My 67 chevy c10 lwb originally had the inline 6 with 3 spd overdrive on the tree. Okay dropped in my 350/th350 and everything lined up perfect. I lined the motor towers with the 2 holes closest to front end. and the trans crossmember lined up perfect. Now the problem is my 2 piece driveshaft does not reach the trans. Its about 1 or 2 inches away from it. I thought maybe I would have to move the mounts closer to the firewall but I dont think the holes will line up with the towers. I was told I would have to take the driveshaft to get it extended. Just wanted to see other people thoughts or ideas. Thank you
