Yes you can see them on page 2. He did a nice job on them, they clear the heater core box.

Today I made a stop for the brake rod. I used the piece that was cut from the clutch cylinder bracket, a piece of 2" exhaust pipe and the stock vega rod.
I also moved the handbrake handle back about 70mm as it was interfering with the shifter stick.

Very nice job on the master cylinder/clutch master bracket, looks like a factory item! :th: opens up useing the later f body stuff with it, wait till you get down below,its fun trying to fit the slave cylinder and linkage in there too, although it matters if your running the lt1 or ls1 set up,since they are differnt, nice work so far on your car!!

Thanks!
I have the LS1 setup so no linkage. It is still very tight where the hose attaches and around the bleeder screw. I am planning on drilling a hole in the floor to get easy access to the bleeder screw. That way I could even bleed the clutch myself.

Time for some updates, a lot of things going on but nothing is really finished. I have been scraping the undercoating off and cleaning the undercarrige with lacuer thinner, nothing I am looking forward to do again.. Found some rust spots in the rear wheelwell areas that needs to be taken care of. Other than that the sheet metal on this one is in pretty good shape!
You can see that GMs primer dip did not work as intended. Above the rear end is a big spot that never was coated.
I also made a simple jig and cut the brackets of the stock rear end.

Today I finished the rear crossmember. It connects to the thick metal area in front of the lower control arm mount, and to the diagonal bars for the main hoop. The LCA mounts are going to be reiforced too. I made the lower part removeable and cut channels for the brake and fuel lines.

The rear control arms are almost finished as well. Bought spohn Del Sphere pivot joints:
http://www.spohn.net/shop/Del-Sphere-Pivot-Joints/
Pretty cool, unlike normal uniballs these can be disassembled and rebuilt. I bought tube ends along with these that were welded to some tubing.
After lots of searching I finally found tubing in the right dimensions to be used for end spacers and sleeves. Without a lathe it took a while to make the 24 pieces..
This solution turned out kind of expensive and heavy, each complete controlarm is about 500 grams (1lb) heavier than stock. I still think it turned out good. They will be way stronger than I ever need and they should last forever..
I have sent the tubes and sleeves on zink plating. They are going to look killer when done!
The swaybar is going to be mounted with some kind of clamps instead of directly through the LCA to make adjustments easier.
