I'm going to throw in my 2 cents now. Use the V8 crossmember. While you have it out, you can clean, repair (if needed, check for cracks in x-member), rebuild the steering, suspension, brakes, & whatever else it needs before you paint it pretty, mount the eng/trans on the crossmember & raise the crossmember into the car, or, lower the car onto the crossmember as it's done at the factory. If you can set things up like that, that's the way to go. Check out Jasperjacko's thread on his Modoba. He & the lads really put a nice ride together. There are plenty of people on this site to help you over the rough spots. My credo is to "Do it once, do it right, & weld the hood closed!" the last part is for effect, but you get the general idea.
