This hitch setup uses 2 x 3 inch thick wall square tubing. The tubing is 1/4 inch thick. The flat plate shown in the pictures is 6 " by 8" by 1/2 inch thick cold rolled steel plate.The frame flanges are 1/4 plate.
The New cross member uses the threaded boss's and 4 original bolts and uses two additional 3/8 grade 8 bolts thru the third hole in the frame on each side.
The tow hook bosses were cut from the original sheet metal cross member and welded in place. The receiver and chain hooks are made from forged d-rings and Square tubing. The clearance to the stock engine exhaust is about one half inch and ground clearance is 10".
The stock cross member is not used and the New One weighs about 20 pounds more than the original.
The rear Valence is a S-Mann unit ,and is avail from many sources.
The metal parts required cost about $65.00 and this setup requires about 2 and a half hours fabrication and R&R time.
This hitch will support or pull ANYTHING the SMART can deal with.
