302 in a ranger

my grand father has a 1989 ford ranger it has a 2.9 v6 in it but i want to but a 302 but not sure what i need. Do they sell motor mounts or do i need to buy a new k member. i know i need to but a bigger rear end. i want to run a stroker 347 motor and a c4 trans with a 3000 stall but do i have to hammer the fire wall to fit the c4 and do the sell i trans mount for this applcation or do i have make my own.. im almost sure ill have to get a custom drive shaft.

has any one done this before??

i dont plan on drive this pickup every day but i do want it too be street legal
