I was wondering if anyone has used
this OER crossmember?

I am rounding up parts to change my '68 c10 from manual trans to a TH400 slushbox and can't seem to find a good original crossmember.
I keep missing them on the parts board.
This looks like it [might] be a good option.
When it's done I want it to look like it's original so I don't want a tubular unit.
Anybody have any experience with these crossmembers? Quality, fit, etc.?
Any input is appreciated
