Hi, All -

Can anyone give me a brief description on steps to replace rear main seal on original '41 Ford - engine in car -? i.e. remove tied rods to lower pan, etc. Thanks so much!

Also, thoughts on power steering for this ride (wife's car)?

Kinda new at this, so if it's not coming our right, pls let me know,
