Those stands had the driveline sitting a little farther back and outside the range of the ATS crossmember. Those frame stands also had other issues with my setup. I dont think they had any offset to them.
Anyway, dimensionally I think you may be ok. My only less than great comment about this crossmember is it seems to flex a lot. Mute point for me now since I'm moving drivetrain back which will require custom crossmember  |
Thanks John for the feedback. Glad to hear it fit okay for you in a similar setup(I have an OE frame also). Seems like it would just by looking at it. I'll know for sure next week. I can see how it might flex. That could a be a bit of an issue considering my new ZL489 motor should be fairly stout.
What HP/TQ numbers were you seeing that caused the flex? Do you think the main source of the flex is from the side brackets(which I might be able to strengthen) that bolt to the frame, or the bar itself?
