Team 321 IRS Subframe. Let me just say that Dave did an outstanding job working with me to completely one-off the design for this build. I spent 3-4 months designing and redesigning with him to arrive at this design. The quality of his fabrication is exceptional.
Shockwave air bags, upgraded CV axles and custom powdercoated control arms.
Full Tilt IFS, c/w air bags, power rack & pinion(which will need to be custom mounted)
Now for fabrication!
I plan to run all wiring inside the frame rails, so I drilled a 3/4" hole where the IRS subframe meets the frame rails. This will allow me to get all the way to the back.
IRS is 34.5" wide and the IFS needs to be about 30" wide. I notched the frame rails about 12" apart inside and out, heated up the joints, pulled them in/out, squared them up, levelled them and then welded down the joints.
And the finished product, with the IRS subframe squared, levelled and welded down. Ready for the IFS!!
Measured up the crossmember for cutting
Tacked into place
Measured up the top hats for cutting
Mounted the control arms and spindle for front and rear. Measured from the floor to confirm frame will sit level.
Tacked the top hats into place and ready for test fitting
Control arms & spindle sit level. Measuring must've been good...lol
IFS welded down
Frame ready for test fit to the body!! I would like to point out that I will be cutting off the portion of the frame behind where the IRS mounts to the rails. For levelling/squaring purposes, I've left it tacked all the way back. Still need to tack a tubing gusset between the IFS and IRS for rigidity and future tranny mount. The rails in front of the IFS are rough cuts, as I need to allow enough metal to support the front end, and the part of the floor where it rises to meet the front nose.
Back to the bodywork.
Removed the next section of floor to make removing the engine/tranny easier.
Engine/tranny out
Last piece of the floor cut out
For the next while I will be removing and cleaning up the body edge lines so the frame will mate up to it cleanly.
I will also cut the excess rail off the back and do a full mock up of the front and back suspension before I slide the frame under the body to confirm my wheelbase, clearance to the body, get wheel measurements...Yes, I know, I should've done that before I welded it all down..lol. Should be good though.
