What are you using to weld it with ? Stick or wire feed? You should be able to pull the carrier and weld the spiders while in the carrier . Some people just weld the spiders in the corners both sides if you can . I like the plate way with a small plate that fits inside the spiders and weld all the way around. Make sure to clean the gear oil out to get a clean weld then clean out any flux or slag when done welding.
