Has anyone used the bolt on frame connectors from Y1?

Not sure about ones from Y1, but most I have seen advertised require modification to fit a conv.

any of the SFC on the market are for the coupes. The verts have an extra cross support that is in the way. You can measure, cut notch and box the after market ones, or measure and build your own like I did.

If you ask me... I went a little bit over kill... but these things aren't going to fail!

I have some pix if anyone would like to see them, you can email me or leave your email address here, and I'll send them. The pix aren't great, but will give you the idea.

Good luck - Brett - 67 Drop Top 455!
