What type of Bigsby?

suspiciousminds

Some time ago i picked up a Hofner HE179 prototype that was made in the early 2000’s.
It’s basically a jag shape, sunburst, 2 humbuckers but Hofner dropped the idea and sold off the few that they had made.
It’s pretty neat but i fancy fitting a bigsby (with a vibramate so as i dont need to drill?)
Anyways, it looks like theres plenty of room for one but what do i need to look for when ordering one?
There seem to be several types available.
Distance between the bridge posts?

Having done a quick google of your guitar to see what it looks like I reckon you'd be best off with a Bigsby B5 trem and the vibramate V5-ST.

Measurements i'd check are how much room you've got between the tailpiece posts and the scratchplate. Just doing a quick measure of my B7 and vibramate: From center of the tailpiece posts you'd need about 25mm clearance on the right and 10mm on the left.
