here's astep by step:
1. get a 636 03-04 subframe, and aluminum plate stock 6"x 6"x 1/8"
2. cut the tabs off at an angle,top rails angled out,bottom angled out,leaving enough length to work with (refer to pics). There is no real right length for this, but make BOTH sides the same.
3. cut the tab pieces the required amount to correct for the angle offset and seat placement(extra 1/4") and discard.
4.cut the aluminum plate to get the correct offset and placement to ease welding time. these plates are cut up like butter with a hacksaw.
5.clean the ends to be welded with sandpaper or wire brush grinder, to quicken welding time once again.
6. take to a good welder that understand what you are doing.
7. grind off imperfections from welding, prepp and paint to your desire.
8. re-install
Piece of cake!
circled in blue are the cut tabs. correct angles and cleaned and ready for welding.
circled in green is the cut fabed aluminum plates for the offset.
circled in red is the leftover rail pieces.
this is a top finished tab rail. the yellow shows what I mean by offset and how the plates come into effect.
the top rail needed an extra supprt plate. this being a project and not sure about stress points and all this was a good time to add.
this pics shows the direction of the cuts relating to offset.....the top had to come out.....(15/16" for mine) and the bottom had to come in .....(9/16" for mine).
the top rail actually went beyond the piece it was to be welded to , so the extra top plate was needed.
Hope this answers the rest of your questions......anyone wanting to try this , I will help best I can.
