Looking good! Won't be long now before you get that new chassis on the road. How do you intend on lifting the tub onto the chassis?

I am hoping as it's fibre glass and only a sport tub that 4 people will be able to lift it, before I installed the seats and the fuel tank, three of us lifted it into position on the current chassis.
 
Have finished the steering shafts, spline has been added to steering column shaft of the 40 series to which a bearing has been added to the bottom end of the column housing. I have added half of a 75 series uni joint combined to the half of a 80 series uni joint with the attached rag joint. I am then using a intermediate collapsible 80 series steering shaft with a uni joint which slips straight onto the 60 series power steering box.

The length adjustment is on the 40 series column shaft which is splined, I know its to long so I can simply cut down the length as required.
There has been no welding involved so the harden steel shafts have not been compromised and does not need to be re-hardened, it also gives me the added benefit of having a collapsible steering shaft for safety.

PS. I also have a small amount of adjustment on the uni (top & bottom) of the 80 series shaft where it connects onto the 60 series power steering box.

Also re-wired the Pre Heat Timer plug on the HJ47 wiring loom by installing the larger plug that is required for the 12HT Pre Heat Timer. I then used a multimeter to check the wires went back to the correct corresponding connections.

Next I altered the 2H FCR (Fuel or Edic Control Relay) as the 12Ht does not have a Edic motor but a VSV 12volt vacuum shut off actuator on the butterfly in the in take manifold.

Must give Rudi credit for helping me solve this problem. Here is your diagram with an explanation in color. I used different colors because in my world Red is always +12V. So RED is battery voltage that goes through the M relay and stops at the ST relay.
When the key is off, the voltage stops on the S terminal which you don't use.
Key in the IG (run) position = power (blue line) to the transistor circuit (including the OPS) and the D terminal is 12V (for your VSV).
Key in the ST (start) position = power (green line) to the middle relay which switches from D to OI terminal (for your VSV).
So now you have +12V intermittent on the D and OI terminals. But there is a minor problem.
The M relay is in series and your VSV is not going to like that. So.... take out the M relay and jump the coil contacts (red dotted line).
As I said before... when the middle relay flips from D to OI there is a split second no power to your VSV.
I don't know if that is a problem. I think not but you never know.

So I jumped the "M" relay coil.

Done.

So "D" drive (green) has power on when the ignition key is ON and "OI" overinject (yellow) has power on when the key is turn to START, so you join these two wires together and connected them to the VSV switch. When the key is turned to OFF the power is cut to the VSV switch and vacuum actuator closes the butterfly

"M" is bypassed on the circuit board and "S" stop is not used

Brake connections to front & rear axles connected, clutch slave hose also connected and the extra long starter motor battery cable connected so to reach the left hand side mounted battery, as the right side now has the air filter, (this is opposite to where the air filter is situated for a 2H diesel).

Great build .. Very thorough . It should handle well & go pretty nicely with the 12ht up front now.
 
The reason for the swap of left to right on the brake calipers is because of the rear panhard obstructs the brake line connection, this is why they are on reversed sides. The part rubber brake hose connection is so when I bleed the brakes for the first time I will simply pull them off and hols them the right way up. It not that you bleed your rear brakes every month?

The only reason I noticed was I had to do the same thing on a 1970 Buick Skylark. I put disks on the rear, and couldn't put the bleeder on the top - so I'd remove the caliper, put a piece of steel in the caliper (so the piston wouldn't pop out) and bled away. Eventually, I drilled a hole in the top then threaded a bleeder on the correct end....in any case, that car was a b**ch to bleed.

I guess, if you're careful, you could reverse bleed it...
