Back plate size for bald eagle spider

[Rockchuck]

What size back plate do I need for a bald eagle inboard spider d1-4 . I read where the bolts holes inferior with the studs. Anyone have any ideals ????

Do you already have either the bald eagle spider or a D1-4 back plate? It will work with a regular 6” D1-4 back plate. If you don’t have either yet, I’d suggest the extra thick D1-4 back plate and then just drill and thread it as the spider.

Bolt it to your faceplate, You are never going to use it anyway.
