Alright, so its been a while since I've made any progress with this lil project of mine. Now I'm to the point to where its time to modify my frame and I need some measurments.

Could someone get me the distance of the tube that goes around the header on the 87+ frames? I need to know how long the bottom "Y" part is as well as the top single piece. then I will also need a point of reference to weld the bottom of the "Y" to the lower frame.

Also why I'm doig this are there any other modifactions that I should make to my frame?? reinforcing weak points etc.
