    As you can see by the pics I have been busy working on this truck. Here is my question. The engine cross member is riveted in so I decided to weld the edges of the cross member to the frame. Also I did the same with the front most cross member as well and welded some angle plate to tie in the frame and the front cross member. Then I looked at where the springs mount to the perches in the front and they are riveted too. Should I weld these to the frame as well. Also the front cab mounts (above the perches) are also riveted in. Should I weld these in as well. I know some flex is good but I hate rivets. Thanks. See pics of progress. [​IMG][/url]

    Id grind the rivets off and replacethem with grade 8 bolts. I did it to my front crossmember and im thinking about doing it to the rest of the frame butt itll be alot of work.

    grade 8!!!
    welding to the frame isnt a good idea when the holes are already there...the previous owner of my truck decided to weld the transfer case crossmember to the frame for added support. what a pain in the asss when it had to come out.

    The rivets are still in their place. I figure that the crossmember has been there for over 17 years so it is not going anywhere so why not add some strength and support to them. If I have to ever remove the crossmember then that is what my plasma cutter is for. Yes drilling out the rivets and replacing with grade 8 bolts is a good idea. I may do this but while I have the engine out I think getting in there and welding will be a little easier right now.

    Not to cut you down or anything, but you've got some serious cleaning to do before you weld anything.

    Rivets allow the frame to move a little w/o tearing stuff loose like welds can do. I'd leave the rivets alone except where you need to remove them for some mod.
    Same for welding x-members in. Unless you can structurally reinforce the whole frame so that it's one rigid piece I'd leave them alone. Bolt any braces in place.
    Fish plating cracks is a different deal. Try not to cut the plates with edges that are straight across the web or the flange of the frame, cut them at angles or even do a flat 'fishmouth' to them. The idea is to not create new places for cracks to form.

    I do see clean metal so I assume there's welds there. My eyesight isn't THAT good.

    Yes I grinded the spots to be welded. From the pics it looks all rusted but I made sure the weld points are clean with a nice grinded surface. Also when I cut my steel I square it up on the Bridgeport Milling machine when I can.
