i have had both SE and DE rams. the SE ram did not work for me no matter what i did, but then again my front is welded (cheap ass). the single ended ram was a farm ram so that might have been my problem. After being frustrated as hell i decided to try a DE ram. I found one at Surplus Center I is a 2.5 bore and 8" stroke to my door was $220. the ram also has mounts already on the cylinder so it makes it easy to mount with (4) 9/16" bolts. it might or might not work on your application but it has worked perfectly on mine. As for a pump i just used a factory chevy pump drilled out and a regular trans cooler. it has worked great and has never given me a bit of problem, a big suprise especially since my stering links are homemade and my front is welded.
