Conversion of 8.8 rear end

[Rsanter 152]

I wish I had better pictures but I will show you what I have.

this rear end was built for a friends track car which is a late model mustang but this applies to those of you that would put a 8.8 into a vintage ford

 

key issue is that on a track car having the axles held by a C clip, the ends of the axles got pounded/mushroomed.

we cut the axle end she off and welded 9" axles end on. We also took the original 28 spline Posi out and installed a 31 spline Posi and 3.73 gears. This requires the use of a fixture to be sure that everything is in line as it should be.

this means we now use 9" axles as in the ford world 31 spline is 31 spline as I bet they use the same equipment to make the new car axles as that made the 60s axles

 

we also welded the tubes to the center to prevent the blue welds from braking under heavy braking/acceleration.

the 8.8 center section seems to be a high quality cast steel so we preheated the area to over 240 degrees and it welded beautifully

Nice work.  What plans do you have for the suspension mounting?  I am going to tackle my 8.8 swap later this year.

This one will be installed in a friends car with a torque arm, panard bar and coilovers
