[QUOTE=SSedan64;1594496]A 200-4R would be a better choice.
You'll need a different Crossmember & the Frame Extension but, can use the same Driveshaft. The 84-88 Montes/ElCos came with 2004Rs so finding the Crossmember & Shifter, Cable & Bracket is easy. Summit sells the Extension or you can make one.
