Been through the Buggy ID, but cannot find a match, any help would be appreciated.

Maybe a Sears Rascal?

This is a Sand Piper, now I cant say for certain who manufactured it as that is a bit tricky. Lincoln industries may be the source so check the underside of your hood for a sticker with a mirror and post back if you find something. Kellison also built these as the Sandpiper - also known as the Sand Piper SP1.
Kelllison used that windshield design. The tail of this body is very very early Manx and was lifted from one of the earliest pirated bodies - I'm getting ahead of my self - lol sorry.
Lincoln and Kellison are linked and I believe are the same company, Lincoln may have been the factory end of his business early on, I am not sure. You are safe to call it a Kellison Sandpiper, but do look for the sticker because if you find it and you should, it would also be safe to call it a Lincoln Industries Sandpiper or Paradise Motors Sand Piper as they were sold through Paradise Motors. Any way you cook this  its a Sand Piper.

Kellison did change the tail design later on because of the Meyers suit so you can also go with it is an early body Sand Piper.

For those reading, it is one of these early Sand Pipers that Terra Buggy copied for their Coyote, they later changed some design details and that's how the Sears Rascal was born

Wow, excellent information.  I will check the hood tonight. Thank you!
