The start of the frame repair.
Removed most of the rivets by grinding the head of with 4.5' disc grinder.
Had to cut heads of some with the torch. Pried the brackets off then ground the remaining rivets flush with the frame and then knocked the out with 3/16' punch and small BP hammer
Had the local steel shop break a few parts.
Used 3/16 plate for all parts.
Removed the spring hangers and flatten out the flange on the triangle bracket. Easier to use as pattern.
Had the SS water cut and bend the flange on the on the bracket.
Used the old bracket to mark the holes for drilling.
Found some 3/8x1 round head rivet at a blacksmith supply store. 50 rivets (2lbs) for $10.50 plus freight.
Had the SS break the 61" long rear cross member (actual length 59.75")
Cut the tail light mounting holes with jig saw. Drilled 3/4 dia. holes in the corners and cut into the corners. Marked the holes with a carbide scribe. It is amazing how close to the line you can come. Very little clean up. I used 3.5x glasses to see better ( old eyes)
Measured the other holes from the original member and transferred them to the new parts for drilling. Used pilot drill 1/4" them 3/8"
Should be able to start assemble soon.
It amazing how accurate the holes and layout dimensions are on the original parts. I think Toyota engineers must have worked with tolerances of maybe 0.2mm or 0.008". on the frame parts, amazing, and this largely without computer controlled machines.
The cost of the rear member was $70.00
The two water cut brackets $75.00
This included the material and the shop time to break and water cut.
Thanks jb
