Looks like SP would be the way to go, most likely cheaper than Trumpeter sprues even if you could get them. Here’s some images I’ve collected over the years, I’ve had in mind to do a T-80 set up for snorkeling as well.
Oh wow, thanks for those! I’ll use them for sure! I did order the conversion kit from Australia. Funny thing is that it’s cheaper to have it shipped from Australia than the US… and I’m in Canada! Go figure!
No problem Frenchy, I appreciate your desire to assist me!
