I got my split wishbone mounting plates from Speedway today. They came with four mounting holes drilled in each. My frame is boxed and I'm wondering if I can drill through both sides and bolt these on with some (grade 8 I would think) bolts or, since there are no "anti-crush tubes" for the bolts to pass through, should I weld the plates on. I don't want this stuff busting loose going down the road. Stupid question #472 for me. Thanks, JH
drill the holes big enough for your "anti crush tubes" to pass through and weld them in, then bolt the plates on.
That's what I would do.... I would chamfer the ends of the tubes so, once welded, I could grind the welds flush...especially on the side where the plate bolts on.
All of the above. The BEST way to do it. I usually don't go nuts with the grinder when cleaning the ends of the tubes after welding. If you do any grinding at all leave a small amount of weld just grind it flat and parallel to the frame surface. Frank
