Frame Connectors

I am thinking about geting some connectors for my 70 Dart. Has any body got a set of Mancini Racing's weld in kit? How are thay?

Also what ones do I need? Thay have 67-69 ones and 70-76 ones. I would think the 70-76 but then thay might be for the 108 wheelbase car and that means I need the 67-69 ones? I wish thay would be more clear about it.

Thanks,Russell

I've got the mopar performance 108" bolt- in's on my '70 duster,but we welded them in place ..Summit sells them for $98.00..if you have a 111" wheelbase which i believe a '70 dart is,the price is $160.00..wow glad i got a duster...
