Fix strategy for (common?) broken hood on '71?
Where my hood support attaches to the hood on the left side something bad happened. My guess is that while it was up either the wind or someone leaning against it partially cracked the inner fiberglass of the hood and pushed the hood support mounting plate partially into the fiberglass hood. The crack follows the perimeter of the hood support plate that fastens to the hood and is maybe 50% around w/ the remaining 50% still 'barely' holding the hood support. Is this a very common problem? Are there any recommended strategies to fix it? I was thinking of two possible solutions: A) force the pushed in part back out to where it's flush again (which will probably slightly worsen it but no way round that) and somehow re-fiberglass it or maybe even cut it out altogether and refiberlgass it in and paint black again... Problem is it's impossible to have any access to the 'backside' of where the hood support broke thru... B) some sort of slightly oversized metal plate that conforms around the inner support ridge of the hood and the support bolts to the reinforcement plate and spreads the load around... Maybe this is not a common problem but if it is - what would be a good approach to fixing it and securing the two threaded bolts inside the hood or whatever... thx |

Sounds like someone tried to close the hood without releasing the "elbow" in the support - and really forced it. I don't have any tried and true suggestions other than perhaps trying to clean and smooth the fracture line as best as possible without breaking it totally free. Then gently depress the broken area so you can inject some bonding compound into the fracture - followed up by using a bolt in the mounting plate and pulling the broken area flush with the surrounding structure. Once cured, smooth the repair and repaint black. Here's waving to ya - \|||| Owen ___ '67BB & '72BB |

The only real way to fix it is to separate the hood frame from the hood skin
and go in from the inside to fiberglass the break. Very labor intensive.

I was thinking along the same lines - figure I'd remove the hood and either cut enough that I can flex it back up smooth or simply cut the whole square out. Once out I might build up enough of a 'beveled' or 'recessed' edge inside the hole say w/ some fiberglass to support the small rectangular cutout. Then simply put some more epoxy down and 'set' the piece on top and glue it in. Other crazy ideas involve placing something inside to reinforce the buildup like say a short piece of PVC or aluminium or something - Sounds like a hack I know but then it's impossible to ever see behind the darn thing and I don't want to remove the entire inner skin. It may not be 'by the book' but I'm looking at an alternative that will last, hold and spread the weight. thanks Owen! |

You'll need to cut a section out of the inner frame to access the repair
from behind the skin. Cut it with a die grinder, seperate it with a sharp chisel (something flat such as a wood chisel or gasket scraper). Put plenty of fiberglass mat & resin on the back of the skin to re-inforce it, then when that sets up go into the top of the skin & "v" out the crack & fill it with resin & mat. Grind flat, & finish with bondo/filler. You can also reinforce the inner structure with mat & resin while you're at it. Glass the inner peice back into place, then when that dries v out those cuts & fill the v with mat & resin. HTH, ~ Paul aka "Tha Driver" Giggle Cream - it makes dessert *funny*! |
