I've yet to find a replacement; the '92 and '93 egr tubes look similar, but they're different.
If yours is similar to the '92, there'* a rigid smooth steel line that runs through the center of the corrugated outside tubing, and I think (but am not sure) the inner tube carries the exhaust to the EGR valve but the exhaust between the inner and outer tube goes to the exhaust, so maybe an outer tube leak isn't critical...
On mine, I used a couple of stainless steel clamps to cover the openings until the happy day when I find a replacement. Nothing else I've found can take the high temps when used to cover the outside of the tube.
