I like the tubeless,alloy mags on the GS450L,would like to find them for my GS450TXZ

I like the style of the alloy mags on the GS450L,they look good to me and I love the "tubeless tire applicable" feature on both wheels;that bike has a 16" rear wheel with a 19" front wheel.My 82' GS450TXZ has spoke wheels,17" rear and the 19" front.I have been trying to find either a 17" or 18" rear wheel of the same style alloy mags as the GS450L along with "Tubeless tire applicable";I would like to also use the same style mag in a 19" for the front.I don't want to directly swap the GS450L 16" rear wheel onto the rear of my 82' GS450TXZ and I want to keep the drum brake rear hub the same as my stock GS450TXZ has.
Did Suzuki make any 17" or 18"(GS450E?) rear mags with that same style as the GS450L using the "Tubeless tire applicable" designation ??
I'm not yet able to upload a pic of that style mag I'm interested in,please be patient with me.

If you cross reference the swingarm part number it shows it fitting a number of different models so a rear wheel might be an easy matter to swap. The front fork on the txz is unique to the bike but if you look at the parts fische you can see there really isn't a difference in the parts between model numbers. If it where me, I'd look at the tx model wheels, they appear to either be cast or stamped.

I am also considering finding a pair of alloy wheels from a GS450E or S model which have those 'snowflake'(?) looking mag wheels.Those models have an 18" rear and a 19" front.Those wheels don't say 'Tubeless Tire Applicable' on them and I doubt it would be recommended to try running them without inner tubes.. I have had a few Suzuki's come in to my repair shop in the past w/ a valve stem installed and tubeless tires(without tubes)on them.The inside beads on those early rims are very thin.. I called my Suzuki dealer back then and they said the word was "unless it says "Tubeless Tire Applicable" on the rim always install tubes.
I just hate 'Having to' install tubes and like Tubeless wheels,less of a pain without the tube.
The other model GS450T with alloy mags, a 17" rear and 19" front is ok too;can I run these alloy mags tubeless with a valve stem installed ??
