gearbox help

[Tedtiler]

Hi lads. Haven't been on here much.  Go easy.

Ive put a roadster lsd into a corolla 6 speed box with the modified gear selector (6 speed roadster bar and reverse block out)

Selector is lovely and all seems ok but no reverse. So I split another celica 6 speed box and put it back together same issue.
im selecting gears on the box, its not on the car. Box was split at bell housing by removing selector shaft first.

I made sure little spring loaded bracket that connects to reverse was in correct place when reassembling.  Little baffled here,  any help appreciated.
