Except , the Super Beetle struts are inserts.
You need the VeeWee strut body to weld to.
Seriously? Did you not get the "insert" part?
Once again. NO pics. How do you expect people to help you with no reference of what you are doing.
The smaller struts were what was used to insert into the existing bodies. IIRC.....
You are actually better off buying tube and mounting the bottoms of the struts to it. And make spring perches.And, AND, AND.,.,.,,,,
THen make a collar to hold the strut in the body threaded on the top.
Please don't do spoob if your gonna put others in danger.
