Correct antenna?

Need a factory correct antenna for my '68 Barracuda Formula S.
Seems like facotry original had the cable exiting from side of
"L" shaped base?
Also, are the pointed clips really needed?
Jim's is the only site that mentioned this.
Jim wants $200.00 for kit.

Found on another site for $115 (no "clips").

Jack's (who I've bought from before) $140.

Also, was original antenna a solid mast or telescoping?

Don't want to "nickel and dime", but want to get the correct kit for best price.

Advice?...Thanks.
