I spent yesterday replacing the original oil pan gasket in my '99 and found it to be a pretty straight forward job. Not as bad as I thought it would be. It did take me 6 hours in my garage. A lift would have made it much easier. So, I found this universal engine support at Harbor Freight and after using a 20% off coupon, it cost me under $60.00 and worked like a champ. After supporting the engine from above, I removed the exhaust Y-pipe, loosened the AC compressor, and removed both engine mount long bolts. I disconnected the steering joints from the rack and pinion, removed the lower stock mount bolts, placed a jack under the sub frame and removed the 6 retaining bolts. I lowered the subframe about 4 inches and raise the engine about 1" using the engine support fixture. The oil pan was easily removed at that point. I used a Felpro gasket which advised against using RTV except at the joints where the front cover and rear bearing cover meet the block. I used a small dab in those areas. Overall, not a bad job and certainly worth trying in order to save the $600.00 I was quoted by a local independent shop.

Job well done. We here at the firebird nation encourage members to do their own work to save $$$. For future jobs, download the 99 service manual at the following link. It has pretty much everything about your bird in it.http://www.mediafire.../?40mfgeoe4ctti

I agree with SeaDog, well done.  Another solution might have been cribbing the tires.

Those are the same type car stands that were used in "how to remove LT1 engine from bottom" article that I found on web.

I forgot to mention that I had to remove the 2 bolts holding the starter on and move it out of the way as well as the flywheel shield.
