CFD Crossmember Flange on Z/28?

[AG1LE]

Does anyone know if this interferes with the Z/28 belly pan? Thanks!

I just put mine back on a little while ago and was looking at that. It looks like the belly pan would need to be opened up to make that work. There are two bolts that go into that cross member as well.

I was looking back at pics in an old post of mine, and I think the absence of those nutsert holes in the cross member is the biggest issue. The flanges would stick down, but it may not be far enough to be problematic (and if it is, I could easily open it up a bit as you indicated).

If you re-use the crossmember and just add the flanges the nutsert's would remain. Might need to re-center the holes on the belly pan though.

I think everyone is over thinking this. It should be fairly easy to do. If you follow the simple instructions posted everything will self align. The crossmember will almost be in the exact position it was originally in. The only difference there could be is the thickness of the blade you use and the neatness of the cut. I haven't installed them with a belly pan personally but what I would do is simply follow the instructions. Before tack welding the flanges on the crossmember put the belly pan in place to verify alignment. Once you have it exact, it should be just about there on it's own, remove the pan and tack the crossmember. The amount the flanges protrude below the crossmember is about 1/4", if it's an issue simply put 1/4" spacers between the pan and it's mounting points.

Good point, that should work but adds a little bit more complexity to the installation. I don't weld, so I would need to find a shop that is willing/able.

I agree, the flanges protruding isn't a big deal.

However, the nutsert holes (i.e., where the nutserts are inserted for bolting the belly pan) are missing from your crossmember. Re-using the original crossmember (which includes the nutsert holes) could fix that problem. IIRC the earlier 5th gens did not have these nutsert holes, but I know they are in the '14-'15 models.

You do use the original crossmember so the nutsert's will remain and in the same location. Look at your car and look at the instructions, it's not at all complicated.

I misunderstood - I thought a crossmember came with your kit. Thanks for clarifying.
