Thank you [MENTION=20520]Jimster58[/MENTION]!
I do see what you mean about how the two dipstick options mount to the transmission. As they're both priced in the $190 bracket (a lot of money for a doggone dipstick, but you also get unburned hands for that price), it seems clear that the B&M product is superior. BTW I priced B&M PN 22200 at B&M, Summit Racing, and JEGS and they all have the same price. You can order it fronm Wal-Mart for $6 more, though.
I have one question about the B&M dipstick, and that is whether it can be used to refill the transmission after servicing it. As the Performance Automatic design permits that, I suspect that it's true for the B&M design. But because refill capability is essential to avoiding burned knuckles, I'm going to call them and ask the question. I'll post their answer here.

I just reread the product description on the B&M web site, and in the parts list they mention "Steel Braided Dipstick/Fluid Fill Tube." I think that answers the question, but I'll call anyway to be certain.
I've already purchased the steel necessary to make the bracket, and I've got a good design working in my head. The trick is to make the bracket so that it doesn't wig-wag around inside the engine compartment due to engine vibration, and with a little (very little) clever engineering that won't be difficult. I'll post my design here.
