Try to find a frame later than '84. The later frame would already have the extension in place to accommodate the 200-4R transmission. As Steve said, the extension can be fabricated if not equipped with one.
Good thing to know. I won't be going back to the yard till next week and I'll try to figure out what year the car is. I know I found a vin decoder somewhere. I'll have to find it again. Thanks for the info
