Hood bump stops

[Bitsyncmaster]

I bought new bump stops from ED but looks like on my car his bolts are to short. My hood does sit pretty high but I can't get the bolts to grab enough thread in the body to hold. Well it also turns out my "crash blocks" don't line up and it also was set to close to the stop and it broke his plastic dome off when I shut the hood.

Anyway, I'm going to make my own bump stops using a commercial threaded rubber bumper (8-32 thread). I will turn some 8 mm 1.25 bolts down on the head and drill and tap for 8-32 screw. My OEM stop is 1.9" long.

Anyway, looks like I need to move those "crash blocks" to line up with the bump bolt. The photo shows my passenger side (look at the rubber ring marking). Drivers side is a little less offset.

I have 1 set of stainless bump stops remaining if you're interested. They work perfectly.

They look to short and I think I want the rubber on top.

Length is ok at least on my car. I was thinking about rubber boots/caps but I like the way they look without.

Chris Miles sells some hood bump stops as well as rear engine cover bump stops. I have all four and they look/work great.

The way I adjust the bump stops starts with the latch. Remove or screw the bump stops all the way in and adjust the latch so the edges of the hood (where the bump stops are) is slightly lower then the fenders. You will have to enlarge the holes in the latch to do that. Now screw the stops up to get the corners even with the fenders. Now the corners won't shake as you drive. When you are done use some black RTV on the bump stop's threads so they don't leak. Line up the brackets so they will capture the bump stops if they ever have to.

I got my 50 mm stainless bolts and rubber bumpers yesterday. I drilled the hole for the 8-32 bumper screw but tapping that hole in 304 stainless is not easy. I ordered some new taps. My old ones won't do it. I turned the bolt head down to 0.125 thickness but still think the bumper may be a little high. Will see if that rubber will cut with my lathe but it may need to be sanded to remove some of the rubber.

Was looking at the engine cover bumpers. Those look like 5 mm screws so I will look into what I can machine to use the same bumpers as I'm using in the front.

I have these and they are perfect and fit flush when installed.

Well the new 8-32 taps don't work either. I'm going to try a forming tap next. What the forming tap does is press the metal around the hole (it does not cut). You use a larger hole for that type of tap. If all this fails I will have to use regular steel.

I just thought of something better. If I can find liquid rubber, I can just make bumpers without any machining. Has anybody done any liquid rubber work? Maybe, FlexSeal.
