Steel caps for 8 3/4?

[TheSwede]

I have a 489 case and missing the main caps, can I use the main caps from my 741 case or is the only way to go to order steel caps? Any suggestion?

The caps are machined on the case so technically, they are not interchangeable....but....it doesn't hurt to try and see if they will fit.
