Default need help with crossmember

ok so here goes. i am looking for a pic of what people have came up with for homemade crossmembers for 80's era chevy fullsize trucks. i want extra beef to keep things from twisting apart. i already built my rear and middle xmembers, im just lost on what to do to replace the stock torque arms that ran from the bottom of the bellhousing to the motor mounts. i can't reuse the stock ones because the big block oil pan is in the way, but i want something to keep the trans from cracking in half. any insight would be great. pics would be better! thanks

You could start with torque arms for a factory big block? Unless you have a aftermarket oil pan.

yes, it is an aftermarket pan. the arms would have to go through the pan to connect. i am looking to instead make a mini x member to go from frame rail to framerail and tie into the torque convertor cover boly pattern.just to hold up the front of the trans to keep it from cracking around the bellhousing.

i have thought of running a front and mid plate but that will eliminate any flex at all. i would like to build something with a bushing to give it enough flex or see what people have concocted to run back to the block or motor mount.

What trans and tcase do you have? Do you have some kind of rediculous motor that needs all that extra support?

i am running a 409 BBC with a 700r4 and 205.not too rediculous. should be around 500hp and a little more torque on motor and a 150 shot of spray for just in case! i just am a big fan of overbuilding everything to save catastrophy domn the line. i have a rear t case x member and a x member that holds up the front of the tcase and the rear of the trans, just want that little extra beef and to not have to worry about cracking the bellhousing along the block. i hae seen it happen without those torque arms and it sucks. lol

buy a frame boxing kit, they run 200-300$. Use some dom tube and a few leaf spring bushings to make some nice and purdy trans/t-case mounts. this will also make them easier to remove for future repairs.

Im of the same mind, build overkill beef. Sounds like your set up should be more than sufficient.
If you still need some more ideas, these were from a doubler build but I like how the 205 is supported. The mounts on the frame are a little bogus tho. May help?..

thanks! that is pretty much what i have going on so far. is there any way i might be able to get a close up of the crossmember in the background? looks like some sort of tube tied into the drivers side frame rail that goes across and ties into the trans and what not?
