Pistol grip ....

I used this on a push in oem box to convert to bolt in handle, Brewer's Performance - Mopar A833 4-Speed Transmission and Component Specialists
Very cool...thanks..! Was it difficult..? I started to remove mine, but stopped after taking out the upper bolt that goes through the box because I could feel it was spring loaded inside mechanism..or at least it felt like it was.. Does it all have to come apart to convert..?
