I recently took delivery of a Jan./1992 CMC speedster that has never been completed and never received all the parts before the company folded.  I do have the manual - the same in our library -but no dimensions are given assuming you already have the parts.  I can fabricate the Front Bumper Support Brackets (2) such as those posted in the manual on page V-8 figure 6 and the Rear Bumper Support Brackets on page V-7 figure 5 along with fabricating the front and rear outer bumper brackets.  The help I need is all dimensions including the thickness of the steel.  Vintage Motors has the parts I am guessing but no photo of them and the shipping to Alaska just about doubles the cost. Thanks in advance for any help out there.

Ed, I can’t get the dimensions today but I’m not going to keep you waiting over 25 years.  Currently I’ve got her front off the ground so it’s convenient to attach some images of the LH bumper support bracket.  They can be used as a fabrication and assembly aid.  Soon I’ll lift her tail, the dirty end, measure and take images of the assembly.  Note - there is a difference in front bracket design of my CMC manual and the SOC resource, V-8, fig. 6, see image (3D CAD).  Is your original manual the same as mine?

 

In the opening sentence the 25 year comment slipped in because there is a SOC member that has a CMC and is still waiting to start the build.  Can’t remember his name but I was thinking I won't keep you waiting for me to start your build. 

 

In the interim ask if I can provide further information or images.

Ed, you'll notice in pic 2 of Dennis's collection how the sway bar comes really close to the bottom tubing of the bracket. In some cars (I believe) the sway bar actually hits the bracket as the suspension moves, so some guys have reconfigured that bottom piece of square tubing. Someone here will have a pic or 2. 

 

And WELCOME TO THE MADNESS! Al

Wow - thanks for the "extra" madness you did to show me another way as well.  Looking at the original version but making a 'notch' for the sway bar looks to be the

stronger of the two versions.  With that extra effort of taking some nice photos Dennis you have shown me how solid it will turn out. Looks like 3/4" box tubing stock comparing it to the size of front end tubes. I've got some solid angle steel I can make the mounting plate with - then add the box tubing out to the front for the bracket's mounting plate. All I think I need now is how long the assembly is since the body of mine is totally separate at this time.  Thanks again....

Attached are measurements of the front bumper bracket bars and plate.  My drafting teacher is rolling over in his grave. 

 

Interesting all measurements are whole numbers.  Indicates CMC might have been paying attention to assembly drawings.

 

Next I'll work on measuring the front bumper mount bracket.

 

I know the first series of images was a photo overload but sometimes it pays to look at the same thing from a different perspective more than once.

Ed, I think Adrian provided what you need.  My contribution could be a reference for installation.  Al made an important observation concerning sway bar contact at the lower support bar when front suspension makes full downward motion such as lifting the of the car.  An additional example for sway bar contact would be CMC drivers that use their car for ramp to ramp jumps

 

Provide an image of your bracket modification.
