Mesa Boogie Express 5:25 short head dimensions needed

Hi,
I need to convert a Lonestar Classic combo to head format and I suspect the Express 5:25 short head shell will fit the Lonestar Chassis chassis, at least after what I saw in the dimensions pdf that Mesa provides to the public.

However, I have no idea if the holes in the headshell for the screws that hold the chassis in place are spaced the same as for the Lonestar Classic. So, kindly asking an Express 5:25 owner to provide this spacing dimensions.

As a side note, if this idea is feasible, I suspect many Lonestar Classic owners might take into account the possibility to convert to short head format.
As you may know, there are no more short head shells available for the Lonestar and the factory built heads in short head format are becoming very rare...

Thanks for your time,
Adrian

You can just call Mesa. That would be your best bet.

I did, no reply yet. Maybe I will just give them a call.

Call them. They get a lot of e-mails and there are only 2 guys there that do Customer Support.

This will not work, as the LoneStar chassis is deeper than the Express chassis. Thanks
