Metco Lowers

[SGRIM]

I am installing metco adj uppers and fixed lowers. Got everything no problem execpt for 2 questions please help if you know.
Please keep in mind rear end is already OUT. So I can not use the directions like they say, take one side off at time etc....


1. Where to drill hole in the ICM brackets?
Do use the template or is the pinion angle different.
If I do use the template which of the 2 holes is correct 4 T/R's

2. Initial upper setting, does that also fall back to pinion angle. How do you set?

If this does not work I guess will have to reinstall factory stuff and start back over

It would be a lifesaver if someone can tell me any tricks on this.

If anybody has pics of after install would be excellent

The uppers should already be set to stock length, you can check this by measuring the stockers and compairing it to the Metco's...you haven't moved the adjustment right?? Hope not.

Personally I would put the rear back up in there, put the Metco's on and keep the bolts loose...Then check your pinion angle adjust and snug the bolts up...Then tack weld the brackets remove the rear of the lowers and weld em up solid...Then torque all the bolts up and see how it launches.

So,

Are you saying do not drill the holes and just weld the ICM bracket to the Rear end once you get correct pionion angle.

These things are longer than the factory lowers when you include the ICM bracket.

How did you get your pinion angle. If I am reading right you measure the angle coming out of tranny and do the exact opposite to the rearend. That would give you a 0 angle though and from searching old posts that does not sound right.

I am a little lost here I hope I do not get in over my head

usually the pinion angle should be set at 1-4 degrees negative and i think for TRs its about 3 degree negative to give you the proper angle. i think you have to do this while the wheels are level on the ground. if you re not sure better just bolt it up close and get it to a shop that can do it properly for you before you have it welded. like jack cottons or other qualified shop.

Well I wouldn't drive it without welding them...I'd trailer it...last time did this we drove it and when we put it in reverse brackets moved and jerked the driveshaft out, LOL.

When i positioned mine- i drilled a hole through the brackets and bolted them up with grade 8 bolts and it held fine until i got them welded.

I am saying I wouldn't drill, I'd weld em...Only saying what I would do.

For the pinion angle you can either measure the rear of the tranny, or the harmonic balancer, either will work, you then compair that to the pinion angle...you want around 3* down just like blues said.

Remember you have adjustable uppers, so as long as you get it close you can change it whenever you want or need.

To use the ICM bracket or not?

I have been reading old posts this morning, now I am really confused. First Thanks for all reply's.

I am to install 2 sets of these. The ones now are going on a street car that hopefully run 11.5's to 11.9's, that is goal.
The other set is going on a RACE car goal is 9.9. Have the motor combo for both goals.

I will also be installing the H&R bar on BOTH cars.

I was reading an old post where sometimes the IAC switch can do more harm than good.

Has anybody ran with and without the IAC brackets.

Honestly one of my main reason for this upgrade is SAFETY!!!!
