Suspension brackets position
Hi guys,
I hope you are all good.
Its time for me to get the suspension brackets in place. I've been checking several sources (book, forums etc) for this and I dont know which is
the best-correct one. After reading almost all info on here I arrive to 2 options:
1) Low quality image that when I draw it in cad does not catch completely (may be my fault):
2) More documented one from http://locost7.info/, but suspension brackets are 50mm long instead of 48mm as per the book.

Any help or experiences would be appreciated.

Do not over plan this element, the top bone needs to be laid back 5-7 degrees from the lower bone to provide caster for self centreing, the shock
ideally needs to point at the lower ballpoint and fit between the legs of the upper bone so build the suspension minus the shock brackets then place
in the best location.
Various sites will show the shock landing 2/3rds along, where you get caught out the shock spring fouling on the top wishbone, a smaller shock works
better here, I have 2 1/4" springs, in hindsight should of got 1.9". Landing back along the lower bone turns the lower bone into a lever
and exerts additional pressure on the brackets.
