Lots of holes/space at bottom of gearbox?

Just fitted a 19 16v box to the valver but couldn't fit any of the 4/5 bolts right at the bottom of the box as there was no bolt thread? The thread which i took out the old box was 2 big and wouldn't screw into the new 1 :( if you look at the bottom you can see the whole bottom of the flywheel :( take it this is going to cause problems?

cant be a 19 box pal, they fit fine

Maybe its an R5 box, you can see the flywheel on the R5 GTT's if you don't fit the bellhousing cover

Says JB3 etc on the metal plate? It looks like it could fit but the threaded bits at the bottom are a different size to the ones on my old box? Can I buy them somewhere??
