Question By: Piet Doek on Nov 29 2019 6:44 PM
These kits are for the 4-cylinder, single reservoir master cylinders only. No one is making the repair kits for the dual reservoir master cylinders at this time. Thanks

No, this is for the 805223 only.

If the bore of the master cylinder is not smooth and has notching or discoloration, I would not try to rebuild. It has to be able to seal the Dot 3 fluid properly.

If your master cylinder is aluminum its not original. Someone has replaced it with something. I would go with 805223 and replace whole thing then.

647801 is the part number for the brake light switch. You'll also need the outlet bolt, fitting and crush washers too if your not reusing your old ones. We have those as well.

The later CJ-2a and the M38 used the same master cylinder so this kit will fit the original.
