Re: (ET) E15 and deck status

[David Brandt <ev_dave13 yahoo com>]

Couple options for you, Chris:

1) Trim width (and the original frame rails) from the frame.  Then weld in 
the angle iron.  This will make the final width the same as the original 
frame.  Attach the mounts and you are good to go.

or 2) cut a notch in the vertical leg of the angle iron at the location 
the mount needs to go.  Cut away the original frame behind this area too.  
Cut the frame away for a little longer than the notch you put in the angle 
iron.  Then fill up the notch by welding in a backing plate of new 
material.  Then weld the mount to that.  Not as pretty as option 1, but it 
still makes the final result the same width.

or 3) go with the original plan.  Weld on the angles, then make new mounts 
with a longer spacing between the bolt holes and weld them on.  Then make 
adapter plates out of excess material for each side.  They will have bolts 
extending up through the mounts and down through the transmission.  The 
ones through the transmission will have to be flush head bolts.
