The pain's in the wiring, I guess. A few guys have done it in the Cressida, mostly in Australia though, where it's easier (Right-Hand Drive donor car + RHD recipient = easier swap).
There are some sites online I believe its suprastore.com that have the wiring harnesses for ya so you don't have to go through the pain of rewiring or whatnot.
i know ref's r evil mean vindictive people. that and they hate swaps. thats why im doing supercharger so i can take it on and off with the smog . same with headder
