Yep. Sounds like an issue with the Indy arms. I use t&d and not sure about differences except better quality in the t&d. Been running them on my 360-1 for about 8yrs with shaft oil plugged off and spraybar oiled only. Some street use with lots of idleing no issues yet. I bought mine from compu-flo for about 750-$800. They list for $1100 last I checked.
