Forgive me for the grammar, it's late and I'm kinda tired .....
Note: These aren't an exact design, just to give an idea of what I'm thinking about.
I have been thinking about making some braces of my own, with the help of my father. Anybody got a pic of an MN12 with a full-set of JL's braces installed? I have no intention of trying to rip off a product, I'm just trying to get an idea of what points need reinforceing.
First, the lecb:
Instead of mounting it with one plate on the bottom of the engine cradle and one on the framerail, how about making it with one plate on each side of the framerail and one on the bottom and back of the engine cradle, therefore spreading the load out and making a stronger mount. I.e. the framerail mounts are in double shear, and you have two anchor points on the engine cradle as opposed to 1.
Secondly, my idea for an IRS LCA brace:
Bascially, you tie all 4 rear lca mounts together to prevent relative fore/aft and left-right movement of the LCA mounting points. Tie this brace into the main framerail or sfc system to prevent movement of the IRS assy relative to the main chassis structure.
Finally, I don't have a drawing for this one yet:
1. Bolt Jack rails along rocker panel flange.
2. Braces bolt the jack rails to the main chassis.
3. Extend the main framerail rearward to the IRS subframe mounts.
4. Kicker brace from #3 to the above mentioned IRS LCA brace. (Kicker brace bolts to the SFC assy and IRS brace facilitate IRS removal.)
5. Tie the 2 main framerails together with a some sort of removeable lateral or x-brace
