Reposting for CSPCRX

 

So im looking to see if anyone has any pictures/dimensions of the front bumper slider bolts that hold the top corner of the bumper up on a 1st gen CRX. Im looking to machine some up at work but im not sure exactly what they look like. I figure ill make them as close to factory as i can. I can also possibly make some for others if they need them once i get the concept down.

 

Thanks!

I can pull the bumper on the 85 and get some measurements.  Not sure if Greasemonkeyreborne 5x1gs has one sitting around as well.  Hopefully he will chime in as I know he has lots of parts.

Sorry haven’t had a chance to pull the bumper, been crazy busy.  On my list still, another member is also looking as he knows he has some in a box somewhere.

Okay lots of photos and measurements for you here.  Measurements are what I think will help you.

 

first is the bolt itself, entire assembly is metal and all one piece.

Hex side is flared, like integrated washer.

Next is the slot the bumper actually goes into it.  Here is the size of the slot and how large it is inside.

This is the diameter of the larger flare that tightens against the bumper.

This last flared section goes into the hole in the fender and bottoms out against the metal it threads into.

This is off of an 85 CRX,  not sure if the 86-87 SI is different.  I know the inside of the bumper has a molded piece that attaches vs one that’s molded in

I made these two this past weekend. They incorporate a 10mm hex head. I will attach the CAD drawing tomorrow for anyone that would like to re-create them on their own. They do work great so far. installed as expected and the bumper went on without an issue, aligns correctly.

 

I can absolutely make them if anyone needs them, it may take some time due to equipment availability but i can do it, just DM me. These ones are made from some 400 series stainless i had laying around but i would prefer them to be 316 or 15-5 ss.

 

Either way, thanks CSPCRX and Greasemonkeyreborne for all the help, greatly appreciated!
