Default anyone replace there bellhousing on there th350/400's?

has anyone cut off there bellhousing on there th350 and replaced it with a aftermerket bellhousing.... http://www.summitracing.com/parts/JPT-92452/ A local trans shop by me puts the case on a bridgeport to mill it down. Im wondering if this is possible with a cut-off wheel and some carfull time? I just dont wanna really pay a ton of money to mill my case if i can do it myself. ANYONE??

my next question is....

on the stock bellhousing the lsx TCI flexplate was REAL close to the housing. Are the JW housings smaller in diameter to where my flexplate wont even fit? It says you need to use a 10" converter or smaller but hoping its just cause its thicker by the end? Hopefully someone can chime in that actually has one of these on a lsx car and TCI flexplate!!

Busted the bell housing on my Th400 in my 68 Bird last year and cut it off and put a JW on there. I have a 9" TQ and there is plenty of clearance. I am sure a 10" would fit with no problem.

JW Ultrabells are machined to fit the LS flexplates...but you need a flexplate that fits TH400 converters, diff bolt pattern and not threaded holes.
