you got a smokin' deal if everything is installed correctly
that gas tank would cost most of that money
check with some of the guys here that have running/driving trucks with camaro ifs to be sure everything is right
building your truck on a frame that doesn't ride right would be a shame
it is a lot easier to fix it now than later with your body on it
stock springs with the axle flipped on top, is the same as what i run.
you will need to c-notch the rear of the frame or it will sit on the bump stops all the time.
i would recommend a 5'' c-notch minimum, truk has 3.5'' and occasionally hits the bump stops
my truk axle is even with the bottom of the frame after i got all the weight of the body on it
i would also buy the same year camaro torque bar and bolt it on the rearend and make a support to the factory x-member
as is it looks like the pinion angle may be down. it may not be locked in at this point
i would also remove the trans x-member and fabricate one that will support the front cab supports
the stock x-member supported the front cab mounts, when that was cut out the front mounts can sag
i would also do any fabrication that you need down the road
underfloor master cylinder will require a bracket
58-59 frame is a bit longer up front than the 55-57 frames. not sure what frame it was based on
the stock camaro motor mounts will place the motor too low in the cavernous dog house
check to see if all the spring shackles and the center bolt have been replaced
box the frame
it wouldn't hurt to throw your cab and dog house on to check the fit and wheel placement
i don't see much in the way of a radiator core support
it would be easy to check your stock frame dimensions to fab up a core support
after all of that... then paint it, then run your brake and fuel lines
