Specification (briefly) for this project is as follows:

Total Team CJ restoration with numerous performance and reliability upgrades.



Update report - August 24, 2018
The chassis is now officially rolling!

We have been busy rebuilding the front and rear suspension, steering rack, brakes and rear axle as we move towards assembling the rolling chassis.

Suspension, brake and rear axle rebuild underway
Everything is extremely rusty!


Your chassis has now been repaired, blasted and powder coated!

Cutting out rusted area at rear of chassis

Trial fitting newly fabricated replacement panel

Welding repair panel in place

Inner surfaces acid washed and coated with wax

Chassis number by right hand rear engine mount

After sand blasting back to bare metal, the chassis
has now been powder coated

Time to start rebuilding and installing the
suspension and drive train

The first two photos in the sequence below show how we modified your oil pan baffle. Originally the XK baffles were welded to the pan, which made it virtually impossible to properly clean the bottom of the pan. We cut the baffle out and install brackets with threaded nutserts down the sides of the pan, allowing the baffle to be unbolted to properly service the inside of the oil pan.




Stage One engine rebuild now completed.
