Time for the exhaust system
Purchased a box full of 1 ¾” bends and a length of straight tubing.
To help with cutting the bends on the correct radius, made a simple jig that held the bends and had a guide for the hacksaw blade.

Starting with the head flanges, made another jig to form the tube down to a rectangle on one end.
Welded them to individual flanges and bolted them up to the engine.
Using pool cleaner hose, cut eight pieces to 38” long and tried several configurations.
At least I could get the centre pipes over to the opposite collector within the lengths I had.

Using hose clamps to temporary hold the next tube in place, slowly pieced together the primary pipes. By pushing the flex hose down the tubing until it hit the head, then rotating it to unload the compression on it. I could keep track of the lengths reasonably well.

Before I went too much further, I needed to make up some collectors.
As it just so happened, Jim Cowden posted a very informative thread on building collectors just when I needed it.
From this, I copied the process and ended up with some nice looking collectors (had them welded by a mate).
Thanks Jim

Tack welded the collectors to some 2 ½” tubing so I could mount them pointing in the right direction exiting the rear clip. Than secured the collectors to the chassis, ready for the remaining tubes.

Clayton,
I noticed on your last two post that you have the stock trailing arms from RF. The guys at then race shop that made my headers noticed that my setup was much like yours. They suggested to change over the Delrin bushings for rose joints on both ends, and to go to a beefier link. This makes them adjustable on both ends. The Delrin units will work well on the street but will be stressed on the track.They say it makes the ride harsher, but I can't tell it affects the ride that much. If you plan to track the car you may need larger(stiffer) pieces. Mine are 1 1/4" tubes. Here is the early upright clevis.
Here is the new clevis. This is solid 1 1/4" stock.
Here is the body mount.

Those were only used to dummy up the suspension. I now have rod ends on both ends with the addition of Jims combined L/H-R/H adjuster on the upright end.
There is no rubber left in the suspension, even the front lower inner points now have press in spherical joints.
Only can find pics of the extra housing that was welded in.

With the collectors fitted, now the fun begins in connecting the rest of the pipes.
Had to put a fair bit of thought into the sequence that the pipes will be removed and installed (when finished). Access to spark plugs, clearance to rear clip etc, etc…..
Like my PVC injection.......:laugh:

All tacked together ready for welding. Once they’re fully welded, will refit and finish off mounting the cats and mufflers.

Chassis has been stripped down ready for sandblasting and painting.
After a few issues with the blaster, got it back in two pack primer. Albeit like the surface of the moon….

Now time to panel it.
Plan was to fit all panels temporary (except the floor which was already painted), then remove and paint both sides before gluing and riveting back on.
Bulkhead and cabin lower inner panels fitted.
