Subframe connectors question

Alright guys well kind of have a debacle question going on so here it goes. So I had received from my dad some Mopar performance subframe connectors for my 71 dart swinger. Well I pulled my car into the shop to put it on the lift so we could weld them in. So I know right off the bat it was a little out of alignment but I figured I'll work with it well we got everything mocked up and clamped. Only thing I really didn't like was the rear of the connector would not go all the way up. It is about a half inch from the connector being bottomed out on the frame. I see the reason it didn't is because the bar was hitting the floor pan preventing it from going up anymore, so my dad insisted that it would be okay so I welded it all up but there is a gap between the the bottom of the connector and the frame. Would this make a big difference? I know it don't look the beat so I'm debating on either a) try to cut free the connectors and start over. B) box it in with a plate on the backside and weld it?

I'll post pictures tomorrow but it's been bugging me since yesterday and I feel like cutting it back out is going to be a *****
