Where to purchase a A-500 / A-518

Don't think the 2004r is any easier then the a500 swap.I had to do the same cross member mods,but i didn't have to use an adapter to bolt it up.
I would say the a500 swap is easier and cheaper at this point,from what i have seen.
It doesn't matter to me that he installs a gm transmission in his car,if it was easier i would have gone that way.:icon_smi:
