Default Replacing five pin caps

Just a quick question before I start rewiring and clamping.
I'm replacing the caps in a Pioneer SA-7300 amp, and have come to the two power caps.
These are 5 pin large pots, and the replacements are two pin snap ins.
The 5 pin caps use 3 of the pins purely for support.
I've no problem with the connections, just with how to mount them, as the connections are obviously totally differently spaced, and the caps will need to be mounted on the board, as there's no space anywhere else in the amp.
I was wondering if there was some kind of adaptor/baseplate available, although google has yielded nothing, or if someone has found a way around a similar issue?
I've posted an image of the two caps in question.

I ran into the problem in a Tek scope. You can make an adapter PCB or possibly mount the new snap-in cap diagonally across two pins.
The adapter PCB had to have pins to sit raised off the main pcb.

Thanks very much for that.
Adaptors were my preference, and TBH I thought I'd probably have to make some, so I think that's the way I'll go.
Nice to see someone's already done it successfully, and gives me a clearer picture.
Many thanks again.
