Anyone modified Trans xmember to lower the Transmission ?

My 904 transmission is sitting against the rubber piece at the top of the trans tunnel.. 65 valiant signet .

I was thinking it would be relatively easy to cut out the mount base, fab some steel and have a welder lower the base of the crossmember , where the transmission mount rests.

Schumacher will send me a 3/16 to 1/4 inch shorter mount for 79 plus shipping, but it may not be enough and I can get the welding done for free..

Has anyone done this?? Opinions?

Thanks
