That # isn't a drawtite #, I just checked...
I want one for my '58 1/2 ton.....after some research, it's a Hidden Hitch # for a 67-87 chevy shortbox
I couldn't find my invoice, so I took the number directly off of the hitch. I believe it should be correct.
other than drilling, any install issues I should be aware of?
Not really. The hardest part was fitting the spare carrier if you have one under there.
