Will a 2nd gen S-10 hitch work on a 1st gen? Perhaps a more clear question, will it bolt right in? Currently I am looking to upgrade to a curt manufacturing hitch and a Street scene steel roll pan. Just wanted to get more than 350lbs tongue load with the roll pan hitch. The only hitches I have found that are meant for roll pans AND 500lbs tongue load, are for 94+.
