Are you sure you need to remove it? Can't you use it for the BB/5 speed setup? LockDoc

Re: Transmission cross member.
Looks awful hard to get the old trans out its a 3 speed manual my 5 speed is a nv4500 to heavy to be trying to shove this 250lbs tranny around it looks like a bolt in crossmember is in my future just don't know how i'm going to get the top rivets out.These nv4500 are very tall also .I couldn't find any 2wdrive conversion builds .

Re: Transmission cross member.
Die grinder if you have the clearance or chisel the heads of course you knew that. A auto crossmember is what you were planning for right?

Re: Transmission cross member.
With a 6cyl /3sold combo, there isn't really a trans cross member, just the mid mount one at back of engine. They are a bear to remove with cab on. I did one years ago with a "hot wrench". Last one had the cab off. Bought a parts truck once with a v8 conversion. PO just torched enough to get the engine I. Looked like ass. I sold the frame as is. New owner was gonna clean it up.

Re: Transmission cross member.
I used a cutoff wheel to cut an X in the head then a Air chisel to pop the head and the Air Chisel to push the rivet out of the frame. Not my idea of a good time.
I would like to know how you like the 4500 (once you get it in). i would like to swap out my granny 4 speed in my C50 for a 4500 someday.

Re: Transmission cross member.
Remove the lower brackets first. This will give you acces to x and chisel off the rivit heads on the upper ( main ) ctossmember. I just did this myself. Use an air chisel if you get a chance
