What would you do???

SO heres the problem, I allready have chassis tech upper and lower control arms, and i am going to have to do some major frame work to get it to lay frame. Since i am not that good at it yet i will have to pay a shop to do it which will run around 5 or 6 hundred to do.

Do you think i should just buy the djm lower arm instead? there around 400 bucks.

The sucky thing is then i will have a set of 600 dollar arms just layin around
