How would the slide hammer have to grab on to those tangs there? You can make the slide hammer, easy. Take a piece of 3/8 or 1/2 all thread rod about 18 ", get some industrial, fat bodied nuts and heavy washers. Take a nice dry sturdy tin can, pour in some lead, drill a hole down through the lead same size as a piece of 1/2 electrical conduit, place the conduit down the center, tap pack the conduit into the lead weight by seal caulking or packing the lead around it, affix it to the all thread and make it slide, want a handle? take an old drawer pull and screw some wood screws through the can and into the lead. I had one like this that I made a cats paw type of set up at the end and would sink fat head sheet metal screws into the steel and work out the dents, I would have holes but braze them up. I'm not sure how to grab those tack tangs. On the red truck I took the section off, metal worked it and tig ed it back on.
