Body to frame assembly

[scales]

Hi everyone.
I'm new to the Cobra kit world,although I have been reading this forum for a couple of years . I now have a need for some information.
I bought a RUCC kit ,which was ordered about ...a year or two ago.
I finally got the frame assembly and ordered the body last July. The body was to be done in 30 days...it's now going on 5 months.
When it's completed ,I'll have to get the body mounted on to the frame. RUCC said they will do it for me. $$$$. Which I hesitate to do. Because, I don't want to wait anymore!!
Sooooo...
Is this a project that my buddy and I can accomplish? If so, can anyone direct me to a source of measurments and directions? ( I never got a complete instruction manual.) Or..............
Direct me to a shop in the Tulsa , OK. area, that can preform the assembly for me.
I dread having RUCC do this for me . I want to finish my car!!!!!
I've already lost my body work / paint slot, so you can see my frustration.
Any information will be so grateful.
Thank You.
