i just went outside and screwed the denso lines onto the ones that are on my care and they screw on right. what else would i need to do to convert to 134 a?

You really don't want to convert to 134a. Our condensers don't have enough capacity to allow a really effective 134a conversion. The pressures will be too high on the high side. If you adjust the charge, then you won't have effective system capacity due to what will essentially behave as a low charge. This means that on hot days or when the interior of your car is heat-soaked, when you really need A/C, you will have crappy performance.
You have a really four choices:
1.) Go with R134a and have crappy A/C.
2.) Go back to R12. Most people don't want to do this. I personally have R12 in my garage, yet I don't even use it anymore.
3.) Install a parallel flow condenser. This attacks the problem at it's root. Add condenser capacity and R134a works great. This is the hardest way to solve the problem.
4.) Find a different refrigerant: R152a.
I have converted both my 1990 Vert and my 1988 10th Anniversary to R152a. This gas is completely compatible with all R134a lubricants. The pressures are very, very similar to R12. The high-side pressures are actually slightly lower than R12 at operational pressures and far lower than R134a. Both cars cool great.I have also converted my 1999 Ford F150 and both of my 2004 Mazda6 systems to R152a. I've done a couple of other RX7's sucessfully as well-one for a friend and one for my son. Performance is excellent.
If you are curious, here is a full thread with all the details you need.

R152a is cheap and works fantastic. If you have further questions after reading the thread, ask those questions on that thread so the answers and information are all on the original thread. Installation details start on Post #42.

well the hoses have to be the same as the condensers so denso hoses with denso condenser. however they connect to the car correctly.
can i use the parts i have now for the 152a?
