Tried my HR steering wheel on the HA and seems like they have the same splines. Just have to machine the boss so it sits a bit further onto the spline and take a whisker out of the centre so the emblem fits in.
Also had an old set of venetians for an unknown car that I'm retro fitting to the rear. All the spot welds are drilled out now and the supports fit well just had to bend the bottom mounts to the right angle. Just all the hard work to go.
I have been toying with a few ideas for the viva was thinking of going with torana inspired colours and trim as they all stem from the same family over here. Ultra blue with a gloss black HA GT stripe and roof, and black interior
But looks like I might be going original if the venetians turn out ok. They go well with the old style green. Its just a matter of trying to find the original material or another seat in good condition over here.
I have also been thinking of maybe retro fitting a small supercharger either a AMR500 or SC12, leaning more towards the AMR. I'd be using it on the 1157 engine that I got as a spare.
Let me know If you have any advice or opinions.
