I agree, buying these things off the web can be hit or miss, some things are better done in person. Go to a local shop with your rig, tell them what you want for it, and ask for recomendations. These folks will know off the top of thier head what will do the job for your application, what it would cost to have them instal it, or have parts on hand to sell you to DIY.

1956 GMC 370 dump " 'Tater "
1970 VW Volksrod "the Black Bomber"
2007 Chevy Avalanche
2020 Jeep Cherokee Trailhawk,
2005 Harley Davidson FLHTCUI

I dig all cars, old and new, whether they were hammered out of American iron, German steel, or Japanese tin cans. Being unable to appreciate them all is missing out on a world of great things.
But thats just MY opinion! :P
