Trying to replace the input shaft seal on the transmission. The two 5mm allen socket bolts both rounded out. Any ideas? If I try to drill out the bolts do I run the risk of drilling into the case and contaminating the transmission with drill filings?

 

Try an easyout, works well. Regarding any filings, what choice do you have?

 

Will I got lucky. Put a little heat on with a vise grip and out they came. Now I just have to figure out how to replace the seal. Thanks for the input.
