Hi All,

I'd stay away from the methacrylic glue, it's brittle. I've used lots of
the medical stuff, fractures like glass.  Try a good FLAPS/Body Shop
supplier for a suitable 3M or similar product. Tenacious rhino snot
stuff will do. And try to avoid drilling if at all possible.  Just bond
using them on with lots of C-clamps or spring clamps til set.  I've just
pulled some Jeep Cherokee lips off for a homebrew set.  Rust underneath
was nuts, despite factory finished paint etc. Just tore fender lips out
completely on one.

Full bonding will be less likely to break up lips, compared to screws,
when the Syncro folks start bashing trees with'em. Final point, silicone
goop cures giving off acetic acid, that nice vinegary smell.  Also
initiates rusting. So primer/paint holes well if going that way.
Stainless steel hardware is cheap, don't skimp. Have fun, Tim
