Trying to make True Frags and M79 Grenade launcher work together

[Eaodor]

Ok so my next play through I thought I'd go mainly explosives, and I remembered seeing this mod True Frags which adds shrapnel to grenade and mine explosions on top of the AOE damage effect. I picked it up and another mod the M79 Grenade Launcher and after seeing that there were no author responses to requests for an official compatibility patch between the two I've been trying to make the shrapnel affect work with the 40mm grenades the M79 mod adds to the game. I wouldn't upload this as I never sought any permissions, I'd just like to get it working purely for my own private use.

I'm no expert, my modding abilities thus far have been taxed just by making weapon mods work together in levelled lists and changing a few damage values, that sort of thing. However, after looking it over in Fo4Edit I thought it looked pretty simple, make True Frags a master for the M79 and then I thought it should merely be a matter of adding the shrapnel explosion effect in the Spawn Projectile slot of the 40mm grenade's Data section. Trouble is after I did that and tested it I'm not seeing the wall impacts that True Frag's edits to the vanilla grenades create, so I'm not entirely sure whether its working as I intended it to or not.

I'm hoping someone here might have some insight for me.
