manual to auto help - The 1947 - Present Chevrolet & GMC Truck Message Board Network

CHEVYE · 11-16-2004, 10:57 AM

i got my chassis paint in yesterday and want to remove the old manual x member but it seems to be riveted in, should i just grind em off? i also have the auto x member from my old truck but it`s been awhile and i don`t remember if the holes should already be done for it??? any help is much appreciated, eric.

Drill the rivets out. Easier with your setup. Holes will already be there for the auto-trans X-Member.

Grind the rivets flush then punch out with a chisel.Holes should be there for auto member

thanks

Another way is to use a cut off tool and slot the head of the rivit, like a big slotted machine screw. Then use a flat chisel on an air hammer, or a chisel and a BFH, they will blow off real easy. Put the chisel here ~~~> (l) Hopefully that made sense LOL

CHEVYE · 11-16-2004, 07:22 PM

glock that`s what i was thinking, take a die grinder to it and chisel it off in sections.

glock35ipsc · 11-16-2004, 09:20 PM

Works like a charm!

I tried grinding them off the rivets but I still couldn't get er out. The cab was still on tho. So I got a sawzall and a real good blade ( Bosch- Rescue & Demolition model) It cut like butter thru the member. I cut it near the frame rails so the "Y" section just fell out. But then I wasn't saving the old parts. Not sure what the blade is worth ( my neighbor is a rep & had a handfull of "samples". If I ever win the Lotto, I'm gonna just buy cars & cut 'em up, those blades work GREAT!

That's how I do it, a sawzall and a sledge hammer.

Cut the middle of the crossmember out to where there a just 4 wings left riveted to the frame. Then, take the sawzall and slice the rivet heads off.

Now, whack the wing with the sledge hammer and it will pop off with the remnants of the rivets left in it.

Why ruin the part buy cutting it in half. Take some time and grind off the rivets then punch them out. Someone might be interested in the manual Xmember.

I hate when people ruin good parts
