started off with a standard xr4x4 bumper and a wrc escort cossy that got off ebay for 99p, BONUS :lol:
this is how far i have got today
2 intact bumpers

cut top off cossy bumper

check the fit to 4b bumper

cut the bottom half of the 4b bumper off and married up to the cossy and screwed together.

next put it on the car just to see how it might look.

next stage is marry the corners up flush then to potrivit all together, get the filler out and smooth over were the joins are.
weather permitting more work tomorrow and a update.
