S10 blast front diff issue

[kaylon]

Did a re-build today to get used to how the buggy goes together, quite impressed with how it's made. The rear diff was very easy to get into as is most of the car but...

I can't get the front lower arm mount off...no matter for how long I unscrew the main holding bolts they simply do not want to release from the casing. So I've not been able to get into the front diff. Has anyone else had this issue. Am I going to have to buy a new front diff case and drill out the old one ?
