What Are You Doing To/With Your Car Today?

My car came apart a lot easier than it is going back together. Last night I got the shifter and linkage back in place and also adjusted the clutch. The shifter seemed to be binding and not going into gear. I realized its probably the fact that the trans is not as high as it will/should be because I haven't put the cross member back in and the tans mount. I raised up the trans and the linkage is not binding. The shifter doesn't seem to want to go into reverse but I wasn't going to force it. I hope to have the trans mounted and cross member in later and then well see if anything is changed. I still have to add gear oil to trans. Should I do that before I am even trying to get it in and out of gear?
Reverse issue solved with the help of fellow member here. Loosening and shifting side cover unbound whatever was causing the issue. Last night I reassembled the column to trans linkage and was going to install my H pipe. I saw a couple of spots wet on the block near the 90 degree oil filter adaptor so while the exhaust is not in yet I decided I'll replace the gaskets for the 90 degree adaptor. I am getting close to the end but now I'll have to wait on parts. Any secrets to make the new gasket set seal properly? I've read a lot about people having lots of issues getting them to seal properly.
