Clearancing and fitting side seals to .001
And random pics of measuring end play and pressure testing coolant seals

^drivefast I was hoping it was a ribcase trans because I have seen you can swap out the bellhousing but it's not,it is a 4speed non removable bellhousing .we are trying to make this truck as much possible like a repu,we already installed repu front disk brakes on it and even the brake booster which I didn't take pictures of
I managed to plasma cut the piston mounts of today and will grind them down a bit another day.

the usual trick with rx3/rx4 cross member in the oz cars
( when fitting a turbo manifold to clear steering )
is to take about 75 mm off one side of the rx4 crossmember , and weld it to the other end
then redrill the cut side and remount
( unsure if you welded that one in.. in the rx2,3,4 they mount to sway bar holes )
this will shift the motor over like the rx7 s1/2/3 does and provide room for the extractors

as a side note,, when i built one of these ( b2000 with turbo LPG RESI engine with tall port centreplate )
i used 2 x FC spark side metal engine brackets welded to the chassis where i needed them
( cut shut gearbox shifter position 103mm )
and dropped the s1/2/3 engine bracket onto s1 rx7 rubber mounts
an exact fit,, with inbuilt offset rx7 engine bracket
