SK,
This is lookin SoooooWeet. I remember going to a few Bug-Outs( V-Dub car shows/swap meet/Drag race) & they had these 2 Dudes that would Drag Race each other.They were th only 2 that had V-8's in their Bugs. One guy's had the Motor mounted in th rear like a normal VW & the other cat had his up front , like yours ! That motor was sooo big, He had to sit in th back seat. Needless to say there was no dash !
This build is Bangin' !! Take a step back & a deep breath. Definitely come back to it !! I wanna see this Bug turned out !! You've got such a Great start !!!
* About your glue dilemma .....
Try this ... Use some Medium Bodied CA - in th Magenta label ... Get some Micro brushes & some C.A. accelerator(sold in a brown bottle right next to th magenta C.A.). Use th C.A. to join th pillars together( try to dab it into th seam of th break,between th 2 pieces) & a micro brush (dipped in th accelerator) dab th accelerator on to th joint,on both sides. It will set fast , so make sure that's where you want it when you add th accelerator. That should make a strong joint & if you go a little too thick, you can sand down th joint a little ..... see if that helps .
*Make sure you wipe down th joint after. That accelerator is a little greasy feelin'.
