Default Having a possible bent subfame

The car is a 2001 camaro z28. currently k frame is out of car and ordered a new one and won’t fit. The front of the frame is too wide to fit the new k frame. the old k-frame fits and lines up fine. I’m wondering if the in frame and subframe are bent? Maybe that’s why it fits and the new in frame won’t fit. Also i’ve tried a umi and midwest chassis knfeames and both seem to narrow to fit into car. Is there a way to maybe bend it in to fit the new k frame? at this point just going to put the original one back in. Any help is appreciated.Thanks!

Time to get it to a body shop with a laser frame rack to do some measuring?

can you explain what that means lol? What’s the cost on something like that if they need to straighten out the frame?

If your stock K Member wasn't damaged then it might be your new tubular K Member is off some.

i’ve tried 2 different brands so either i have really bad luck or the frame has shifted or something. When i looked under there nothing is bent or out of place that i can see.

UMI said something like when you take your original k frame off sometimes the subframes can move a little bit

I did the under the car engine swap and dropped it with the k member. When I raised it back up the bolt holes were off. I raised it enough to get all the bolts to all start threading in and it straightened out as I tightened them.
