Congrats! I have been with my wife for 8 years and married for 7, and she is the best thing that has ever happened to me....then my bike...then my truck...but she is #1.
if i were you i would put a boat on top of that Blazer chassis. and ill take the sand rail chassis off of your hands, and then go buy Brices motor....then steal petes wheels....and Bert horn....
water pump and seal....they are not that expenssive, but if you do replace it, replace it with a Boyseen high flow, if your gonna spend the money and replace something, replace it with something better.
