Engine Mounts: Please help

Wow, you guys are so helpful. THANK YOU!!!!

Yes, Cudamark... I thought it would be easy..

I am nearly certain it was an orignal slant six car, I will take pics soon, car is 60 miles away in storage..

I am going to look at the mounts, transmission, carb, air cleaner assembly on a 65 Valiant.. would those work for me?

what should I get from that car? he is going to pull the whole slant 6 drivetrain and convert to 318.. I could buy the whole drivetrain if all of the parts would work.. I was gonna buy his motor but it smokes and knocks, so I bought the A100 engine instead.. Owner swears it runs very well, and said he would give me money back within 30 days if it isnt so. Thus, I am rushing to get it in soon (just picked it up this weekend on May 1st)

So should I stick with the "low mileage, great-running" A-100 motor and get the other parts off of a 65 Valiant, or try to get my money back for the A-100 engine and look for a different drivetrain altogether? Will it be too much work to make the A-100 engine work in a 1966 Dodge Dart GT?

Thanks so much in advance for any help!!
