Nice job on that bumper with the bottom piece and triangular gussets - especially for anti-torque. I am about to pull the trigger on a 60" (58" net needed) rectangular piece of 2 x 4 x 1/8" wall 6061 Aluminum extrusion, weld it inboard of the existing bumper as others have indicated is the 'right' way to do it. I also observed a doubler outboard would accomplish nothing but adding net thickness to bumper, not strength. The T-straps you added at the intersection of the bumper and longitudinal frame member are clever, may consider that, too (after).

Is this what you are buying? I've had this on my Amazon wish list forever and if your install goes well, I'll get one too and have it welded on the inside bumper. Thanks!

Hey, sorry for the slow reply- just saw your question. Check this out from Onlinemetals.com - quite inexpensive, arrived today, 60" length (I need approx 58") Shipped, about $66.00
   2" x 4" x 0.125" Aluminum Rectangle Tube 6061-T6-Extruded   60.0" $45.01 (Part Number 7038) . Now to figure out how to get it welded in, I'd be set !

I live in a small town of 18k in the interior of BC Canada. In our equally smallish industrial area is a fabricating shop. Whenever I need a piece of aluminum stock, the owner lets me rummage through his bin of cut offs. I've not needed but noticed up to 6' of various 2x stock every time I'm there. I predict that for the $45 piece mentioned in the last post, the owner would ask at most $25 ($15 USD!!) 'for their Christmas party fund'. Of course, if I do need alum welded, I know the shop will do a good job. Isn't this scenario also possible in small town USA or is this just a fortunate coincidence for me? GK
