I still have the left over parts. With the legs you are cutting off the first 7 1/2 to 3/4
from the top. Nosure how precise this needs to be, I think I cut 7 5/8 off
With the triangle basically cut it off the base , leave a decent amount at the tip when you cut it, I ended up bending this down quite a bit so it kept the front leg nice and sung.
If you are double wheeling like Troy don't cut the where the wheels going on. I ended up cutting mine, not sure how much on that.
