I will give it a try and post the results here in a couple weeks. Thanks for the response!

Well we slipped the motor and trans in Thursday night. The transmission to trans tunnel clearance is tight without the spacers under the crossmember. I will be changing the body mounts this week which should give me a little more clearance but I would need an additional 5/8 inch of clearance in order to use the spacers. I'm not sure if the chevelle and El camino crossmembers are identical and it just so happens that the crossmember sits higher to begin with due to the boxed frame vs. C channel frame.

The crossmember for the boxed frame cars is quite a bit shorter than the crossmember for the open frame cars, which sit on the lower flange of the open frame as opposed to the raised step that yours sits on. Yes, let us know how the new body bushings affect your clearances.

I will definitely post results. After putting the motor and trans in, I was thankul I went with the Holley ls swap components. I can't imagine the fabrication involved in this swap prior to these parts existence. Oil pan clears the k member, tie rod ends clear the oil pan, plenty of room for the firewall. This is the only clearance issue im having so I'm a happy customer.

Iím glad to hear of your satisfaction, that swap system took quite a bit of time and effort to achieve the level of fitment and functionality that it provides the user.
