I've stripped down everything off my eagle and I noticed the chassis wasn't quite symetrical. It's hard to explain so I've taken some pictures. Does this look like it should? Where's the front of the frame attaches to the middle looks really quite flimsy and the welds don't look amazing.
I'm hoping it's nothing too serious, too late to go back now!
I think this is just how the chassis is. I have a spare Eagle SS chassis and it looks very similar to your one. Also I have found with these cars that the chassis never seems to line up very well to the transmission tunnel, I think this is more to do with a moulding design imperfection. Also rear suspension mounting points look a little untidy. Having said that the chassis' does seem quite solid.
Neither the Ford or the VW versions are symmetrical and can be up to 20cm adrift side to side. As far as the chassis goes the only way is to have a bare chassis on stands and a flat floor and measure it, then bolt on the body and watch it go wonky again.
The SS and RV chassis are the same and follow the VW beetle footprint.
Sadly it is quite common on many kit are and more than a few pre1980's production cars too. I have a Cobretti Viper. The body is fantastic, but the chassis looks like it was made by someone who has never welded before and was way out in some critical places. Chassis design and construction doesn't seem to be a strong point of a lot of kit manufacturers at that time. As mentioned, it is all about having the axles and suspension rigged correctly. The rest is just about how safe you would feel in it if the worst happened and you had a bump in it.
If it were me, and if they would not foul any critical components I would be putting some triangulation into that chassis to stiffen it up. It would pay dividends later and the most noticeable way would be reduction of stress cracking and crazing in your grp shell.
I made this bracket to support the seat belt stalks that are bolted to the rear of the transmission tunnel on my car. It fits between the central longitudinal chassis rail and the under side of the transmission tunnel. I had to make it with 12mm spacer on the offside and a 26 mm spacer the other. This shows how the ford based Eagle chassis and body does not line up perfectly. But then you have to co consider the budget and time the company had when developing a ford based version of the 'SS' My car is a phase 2 and the phase 3 may be different.
This is a picture of my spare 'SS' chassis. You can see from the pictures that the rear spring mounts don't look very well put together. The chassis on my car is very much the same. Also I have found that on the ford based chassis the shock absorber mounting points are further back on the nearside than on the offside.

I wouldn't be too worried about shock absorber mounts. You sometimes find this is a deliberate action by the manufacturer to help with axle location or smooth damping. Not saying it is in this case, but in my humble opinion that is not too much of an issue. I do worry though if you say spring mounts etc are not strong or uniform. But at the end of the day it all comes down to what is acceptable to you to strap your backside , and those of your loved ones to before hurtling down the road at many miles per hour, because while it is the body that looks pretty, it is the quality of the chassis that will keep you out of the hedge :-)
