Must be time for an update. I have just posted the fun I am having with the hq disk onto torana drum stubs on another thread so Here it is again.
The calipers from a uc torana can be made to fit a hq disk using the pad retainer from it's big brother (hz by memory) The caliper will not fit the CRS mounting plate. If you can make a new mounting plate with the caliper rotated 4 to 5 mm lower to the front and away from the stub it will fit. It will also clear all steering and suspension parts lock to lock as well as top to bottom of the travel.
A wb caliper once the alloy ( lets say LH side) part has been put on the other sides cast steel part (RH side) will bolt up to the drum stub with the CRS adapter plate. Swapping the caliper parts is to put the bleeder to the top. I am not convinced that it will clear the steering arm so I will post the result once I test fit them. It will also need custom brake hoses mabe as the WB uses a metric banjo bolt and the UC is an imperial hose screwed directly into the caliper.
I have also worked out that I can get troana pacemaker headers to clear a t400 trans by cutting the trans bell housing on the LH side where the lower cover bolts on and re drilling/ taping the bell housing so the cover can still be fitted. I have the new mounts to weld on the K frame and the cross member for the trans. Engine complete carb to header so I am hoping to get it in over the next long weekend.
The 31 spline 9" now has a tru track center in it with a 3.5:1 gear set and has been set up to fit the car. Alloy radiator waiting to be bolted in.
I need to work out an AC compressor mount once I have the engine in the car as well as make the associated hoses and pipes. The under dash AC that the car came out with has had alloy pipes made to replace the hoses that originally went through the firewall so the rest of the AC system should be easy to work out.
There will be plenty of other things to work out along the way including the wheels and tires. Test fitting the wheels today just proved that they will not fit so I now need to find some HQ pattern wheels that will be in track and clear without flairs. I was planing to try and use old school 14" wheels just to keep the car looking like it would have back in the day. If any one wants a set of 13 x 7 mags that will fit a uc or a set of 14x7 mags that will probably fit a hq to wb let me know I seem to have some to spare now. If you want to swap for something that will fit my uc even better.
