Following my post re your original question you replied what you had done re engine and trans you have fitted.
My original answer is the only one that will work within the parameters that you state i.e. you dont want wider axles.
The stage one axle i mentioned was the front axle assy off a landrover stage 1 V8 this was the last model before the 110 it was a 109 with V8 and permanent 4wd like a 110 or 90 but wth leaf springs.
You dont need to change your rear axle. other than to make sure the diff ratio is the same as the stage 1 axle. and to upgrade your rear brakes to 109 spec. I would suggest that you fit a servo so that you make full use of the braking capacity of the stage 1 front. HTSH
