Default TPI Runner part #?

Are the TPI runners on ALL L98's the same length, diameter and part number? Can anyone tell me the part numbers for the TPI runners for an 86 with aluminum cyl heads?

Long out of production so even if you had a part # it wouldn't do you any good.

Differences are for the Cold Start Injector and I believe a couple of the F-Body's had smooth surfacing.

Here's the best place I've found for replacements and if you poke around you can find their video and writeup on the differences: www.hotrodlane.cc
