I need any info on measurements for putting a mustang 2 front end on i am not sure if my new crossmember should be set at the same area as the axle so any help would be really great
I hope you have not cut yet, you are going to have to have all of the parts so you can do a mock up of the new parts, you need to have the existing suspension in place wheels straight, drop a plumb bob to the floor from the wheel centers and make a mark on the floor, one of the guys here uses a notch into the frame to keep his lines. from there it is a matter of what numbers the parts mock up tell you. There are guys on here who do these in their sleep, they may have fast track ways of doing these, for me I do 1 every 10 years so I do them so micro **** over measure and safe they would go nuts. Do a search under m2 installation, it's a popular post
If you bought a Mustang II kit it should have the proper measurements for the crossmember and top spring cups for your application. The top spring mounts in most applications usualy set 1/4 inch forward so you need to check the proper application and go from there.
Keep the directions..toss the measurements in the garbage. You need to put the fenders back on and just tack the crossmember in. Now get tires and ride height rite. Next up look to see how the wheel sits in the wheelwell.(most don't look rite if you use the directions) Also set caster , camber and rake of ch***is before you weld the top hats in. Forget the direction about caster and camber also. Non power racks use about 6 degrees caster. Power you can go as high as 8. Been cutting "kits" out for over 30 years now and fixing f'ups . They are just a start,if you dont understand frontend geometry it will drive not as good as it could. Most company's dont even do it rite ,they just copy Ford old alignment spec. I could write a how too 5 pages long on how to do it rite,but go find a good racer to help you. Just remember to tack everyting and roll it out and look at it.
You may want to rethink that as 99% of the time you would be wrong. They need to come back and its diff with every car /truck if your doing quality work. If you move them ahead....your losing all your caster and thats simply no good for straight line handling..One of the reasons people have the dreaded steering is too sensitive. Now add some rake to the ch***is you have made it even worse.....
Be micro ****, take your time research the **** out of it and get comfortable, trusted advice from Elpolacko, T Man, Metalshapes, B*** and several others out there, Steve especially is a Guru on the M2 front suspension.
