how close is your... and a story

[midniteblues]

driveshaft too your ta c-member after lowering?

I've been building a trans crossmember from square tubeing so my exhaust can stay above the frame.

another reason i'm doin it is too correct the engine/trans angle

i used oe 68-71 bbc frame stands on my 67 too mount the bbc.

in the begining i figured i would use a oe auto trans crossmember under my car 4spd behind the bbc but i quickly found that the auto cm just wouldnt work. no matter how much shimming i did under the trans mount.

i had over 10 degrees of rear tilt at my carb mount(without any shims.
plus my headers exited dead center of the trans cm and the fan was into the top of the shroud.
and there was no way to shim around 3" collectors

the severe angle kinda baffled me i figured with oe parts i should'nt have had this problem.

i had tried a cpp tubeular trans cm an had both the same problems it didnt change anything.
plus i didnt like the fact that it only mounted to the bottom of the frame c channel. unlike a oe that mounted top an bottom.

so a custom trans cm it is.

i have a ece 4/6 kit on the truck with 1 1/4 blocks out back(total of 1 1/2 block with the ece trac bar mount/shim)

i used blocks in the rear since i'm gonna run a taller tire in the back too level the truck.

i dont have the cab(very soon after this problem is solved),front clip or bed on the truck yet so the only weight on the frame is the drivetrain and core support.

can i set my driveline angle this way? or will the weight of the body drasticly change the angles?

when i set my carb mount flange to level(0 degrees) i have good drive line angles at the rear, drive shaft,and trans.

when i have everything set up with good angles my
1 peice driveshaft is 1 3/8" from hitting my oe ta crossmember(i havent trimmed the top of the hoop) how close is yours?

i'm afraid that as i start adding the weight of the body i'm gonna run into clearance issuses here.and change the driveline angles

anybody have a drop similar to mine on a completed truck with a oe ta c member? how close is your shaft too the top?

i'm kinda up in the air. either trim & reinforce the oe cm for ds clearance
or just get a ece peice an have no worries except my wallet.

i allready have my oe ta cm with 4" schd 80 pipe welded in for exhaust pass through.

i painted my firewall last weekend so my cab is ready to go back on the frame but i wanna get this figured out before i remount it.



i tried too provide as much info to my problem if more is needed i'll give it.

there is so much expeirance here on this board surely sombody has had a similar problems.








so custom it was
