i have even looked at aftermarket add on gadgets for this. they are not that expensive, but require som fabrication.
i am not a rich man, nor do i purchase vehicles which drop much in value, but at one time i aquired a D21 pickup, 86.5 model. this thing had power windows, a/c, a/t, power mirrors, v6, ext cab, 3 way driver's seat... blah blah. it even had 2 fuelgauges... 1 for E-F and one for 1/4 - 0. i loved it. 275,0000 miles and interference motor timing belt problem. (oops to the seller)
non-power is lame. nyahhh.
i am lazy.
there are conversion kits for much less. esp if you just do the front 2.
