Wow that's some serious overkill on that frame!!! Remember, you don't want to make it to strong, it should absorb the impact and crumple, not transfer it to the main frame and rack the whole chassis.

Made some progress on the frame for the front end, until my welder started bird nesting  >:(  Dont know if it needs a new liner or what..it is old.  ::toothy

The steel frame will have another section that will be just a tad lower than the fiberglass bumper, hopefully that will stop the repaired bumper from getting damaged

Cut the front bumper off, shout out to Murci Me for the pointers and drawings.

With the bumper off there will be some time spent fixing the cracks and scrapes as well as the sag.

got the revised Arruat upper strut bracket from my friend  ::toothy  So now the passenger side is installed :)

The Qa1 coil over instructions say use anti seize compound on the threads, but that seems like it will collect a lot of road dirt?

Waiting for the QA1 bearings.

Looking at the front bumper on the REDO it still has the sag.  Will have to take out some steel tubing that has been bonded to the fiber glass fender well to fix the sag.

Looked at Nickmmkk's build, Thanks for the pictures! It should help.  Is the goal to get the rockers in line with the front bumper?

got started cutting the steel for the REDO front bumper.

Using rectangle tube that has the same dimensions as the fiero front frame.  The wall thickness is 3/16.

Started cutting the pieces, but need to get a new saw blade. One saw for cutting length, but the angle saw is great!  Borrowed from a friend.  A real time saver!!

The fiero frame wasn't cut evenly at the ends.  Using a tool to get the angle as both sides are different.

The front bumper needed to come out and be beefed up.

It consisted of a 2x2 coming out from the frame, a 1/8 by 4 inch for the front of the bumper ...tack welded in the center. and some misc, 1/2 and 3/4 inch tubing.

Looked at jets303 set up and it will solve the lack of weight in the front end as the car is very tippy, and maybe make me feel safer,

It came out pretty easy.

Got back from my trip and installed the driver side Arruat front suspension and brake set up.

First is read the instructions and have a cocktail   :D

I ordered the bearing set up for the QA1 adjustable coil overs.

The two lower bolts on that bracket were replaced with longer threaded bolts for my cross brace which connects the two upper shock brackets (RH & LH) together.  Due to limited clearance, I added spacers to reach the support plate which was then welded to the frame rails and then the crossbar was welded to those plates.  (hope this makes sense) ::scratch

I had a friend who owns a fabrication shop come by and look at the Arruat parts and the car.   After measuring the Drivers and passenger side brackets the passenger side Arruat bracket is off by between 3/16" & 1/8".

the drivers side is doable with very minor modification & Murci Me suggested bolts.

He took the replacement bracket that Arruat sent and is going to fix it and have it back to me Monday. 8)

The basturdized bracket will be a paper weigh.

Onward!!
