Thanks Doug
I was by myself and i installed the distributor and it would not fall into
the oil pump, so i bumped the engine without the hold down in place, the
distributor jumped up instead of falling in so thats where the fun began,
Has anyone pulled the oil pan on these with the engine still inframe?

Thanks
