cuase the bracket is already there from a nother truck I got the motor from. and with a 1/4" spacer to move it back, and maybe a long powersteeribng belt it may go with no issues, why make it hard on myself. the chebby alternator I have, used to be mounted to a smog pump bracket and was used in a 80 toyota 4x4 that i bought 2 years ago. the truck i could not smog and parted out, and kept this stuff.
