Two times in the past week when I drove the Roadmaster the hood has popped open upon hitting a bump. Thankfully the safety latch prevented a disaster.
I'm afraid to drive it more, before I can find a solution.
Here's what I've done, am doing about it.
I've found a used lower hood latch assembly for sale on Ebay. I have not purchased it. But, I have inquired on the price of shipping.
I tried running the hood 'bayonet' bolt farther out.
But, that only made the hood loose.
So, I adjusted the bolt back up to bring the hood back down, tight.
I've not been successful recreating the problem standing in front of the car. But, I can recreate it by driving over a bump, the hood will pop open, the safety catch is the only thing preventing it from opening completely (very unnerving!)
I read the shop manual and today I'm going to try to adjust the lower assembly laterally, (toward the passenger side) hoping to give more surface contact between the lower latch and the upper 'bayonet' bolt
edit: moving the latch laterally is not a solution. It only moves the hood closer to one fender. And away from the other
Any words of wisdom, tales of experience, advice, thoughts, are most welcome.
