I can’t promise to lose weight, or drink less beer, or.... but I will drive this Cruiser in 2018!!
Got some time today to work on the FJ60 steering box mount. I’ve poked around at all the conversion threads and tried to take all the ideas I liked. I didn’t just want to bolt through the outside frame rail, and I didn’t want huge plates hanging out on either side. I wanted it to look similar to how it was mounted originally on a 60 series.
First mock up location and trim inner fender. I have a 1/4” plate on the frame to keep the box off the radiator support.
Used some transfer punches to mark out the plate and frame using the box as the template.
I decided to fill in the rear hole in the frame rail with a piece of 3/16” plate cut to size as there wasn’t going to be much support for the bolt sleeves otherwise.
I transferred the holes to the inner frame rail and enlarged them to 11/16 for the sleeves. I used 3/8” pipe nipples (which fit an M12 bolt perfectly) for the sleeve material. The outer holes were chamfered and the sleeves beveled to make for a nice weld joint on the outside, and I left the inner side protruding about 1/8” to get a bead around them. The top front sleeve is encircled by the frame hole, while the lower one has about 50% contact. Should be plenty good.
The spacer plate was cut down to size to match up with the box. Originally I was going to weld it to the frame but I think I will just leave it float as all the holes are very well fitted and there is no movement even prior to tightening bolts.
I used M12-1.25x100 (fine thread) bolts.
One more thing off the list!
