So last week, I was rummaging around at the scrap steel yard, when I found the perfect piece of steel:
As soon as I saw it, I knew what to use it for: the tire carrier!
So, drill 4 holes, 21/32", and then install 3 studs, used for a Sterling 10.25
Cut the two bottom studs off the stock tire carrier, knock the top one out, and drill that hole out to 21/32" as well. Then, press the 4td stud thru both the stock mount, and the new plate. Then weld top and bottom to the tire carrier and viola! 8-lug tire carrier!
