UK Car Repair: MG Midget Question, quarter window, mg midget


Question
Hi there I am kinda new to restoring the 1969 MG Midget I purchased about a year ago and was a tad bit gung-ho in removing a few bolts.  So my questions are----
1.  I removed the quarter window assemblies of both doors and now(almost a year later) have finally gotten back to reassembly and I have 2 bolts on each door that are supposed to be the front glass bottom securing bolts.  What I can't quite figure out is what exactly are they suppose to securing to?  When I go to put the bolt in, theres nothing on the opposite side to hold the bolt!  Am I missing something or have I just overlooked something?

2.  When I hit about 50 mph the car starts to chug and won't accelerate any more.  Ideas?

3.  My oil pressure is low and I can't seem to raise it any.  It was perfectly fine, and then steadily began to drop where it stands now at 10. Thoughts?

4.  And finally, after the car has run for awhile it will on occassion shake and sputter when turned off.  Please help!
These are all things that I have been working on and trying to read all I can to figure it out on my own to no avail.  Please help if you can, any help at all would be greatly appreciated.  Thanks,
PWatson

Describe its present condition and what work will be performed to it before you conceder it done. I will then give you a list in stages of what you will need to do and how to do it.

I will await your reply,
