Re: big block cross member
Jerry,
The small block auto ( 4-speed, Powerglide & THM350 ) crossmember is
the standard crossmember. You will know this one as it has
a race track shaped hole on the underside where the bolts
mount through ( into the trans mount ). The BB THM400
crossmember is of a tubular design ( totally unique ) and the
BB 4-speed crossmember looks similar to the small block
crossmember, however the trans mounting hole is more square-like
with one corner having a protruding tab. Also, the upper
passenger side portion of this same crossmember has a
stamped in recess to clear the speedo cable assy.
Hope that helps.
Nuch
