What kind of fullsize axle? Pass drop Dodge/Chevy/Waggy D44? Dodge/Chev D60? Ford D44/D60 driver's drop?
You can narrow a Chevy to Waggy width and use stock Toy perches.
You can run a Chevy or Waggy as it came from the factory and widen your front spring hanger to match the perches on the axle. You need to run offset shackles.
You could 3-link it and forget about all the perch spacings altogether.
You could run a radius arm ("wristed" or 2-link) with a panhard.
You could start reading. Read the entire FAQ. Read the list of Toy buildups that is the 3rd thread in this forum. You will find builds like Myanarchy's, 300Sniper's, or mine with plenty of photos of going fullwidth.
Do some research, then come back and ask specific questions. Nobody is going to spoonfeed you.
