Plus some additional work blending the rear boxes into the existing structure.

Very nice work!  Too bad I've got my MP ones bought back in 99 just waiting to be installed, lol.

Domino,

Can you please post some more detailed photos of your front torque boxes?

I'm designing my subframe connectors this weekend so i can have a local laser-cutting shop cut and bend them.  I'm also going to have them cut out and bend the front and rear torque boxes and want to see how you did the fronts.

How wide did your subframe connector end up being?  Since the rear frame section is tapered, i can't decide how wide to make them.  At first, i was planning in 2" wide, but now i'm thinking that will look too narrow...

Also, what is your plan for installing you fuel and brake lines that wiil run thru the big slot in the front of the subframe connectors?  i'm trying to figue out how to get tem in there without destroying the line and haven't come up with anything yet.  i don't want to have to cut slots in the connectors and then weld the pieces back in to get the lines installed after everything has been painted and undercoated.

Thanks!
Matt

The front TBs are made from two trapezoid pieces. The larger piece needs a diagonal bend to fit correctly. It has two cut outs for the fender hardware. I notched mine at the front inner corner to fit around the stock torque box and mate flush with the frame rail.
The small piece ties the floor pan to the large piece and the inner rocker to the frame rail. The DVR side needs a hole for the E-brake cable. This piece does not follow the floor pan contour all the way to the inner rocker.
I made these from cardstock templates. Cut with jigsaw, holesaw for the notches...Bent on edge of bench with clamps and big hammer with block of wood.



I don't recall the measurement, but use the bottom width of the frame rail and tap the "U" over it, spreading the flaps...haha. I'll drink to that!

There's a long slot where it mates to the x-member. ( like US tool)that allows the lines to feed through if you put a gradual bend in the line. So I'm told and hope is true.
