There are adapters that we use in our bracket cars

Boy would that save us some money.

I have to wonder if anyone has approached JW for a 904 ultrabell. They do list one for the 727. There isn't a generous number of pump bolts on a 904 but it has as many as a 200 and I haven't had a bell fall off of a 200.

There is supposedly one for sale locally which has nothing to do with me. Pat, now retired, was a big 904 proponent so it's possible he had some made by JW. The bolt pattern looks right, but can't say for sure.

I do have an issue with the trans occasionally getting loose on the adapter on the trans on the 904.
It was in a 440 Roadrunner stocker that I bought. I removed it before
I got bounced back then some years ago. Probably would not make a difference
any more but I will not to care to chance it anyhow!
