Stockys does offer some of the stocks in the older 4.27 spacing and some in the new 4.40 spacing. Some are available for both, others just one spacing or the other and not both. Stockys makes a great stock as I have 2 of the Hart LRT's but their customer service needs improvement. Called over two dozen times since March to get pillars that I was charged for and have not received. Have yet to talk to someone that can help. Would love to order some more stocks from them but if I can't get $10 pillars then what happens when I get shipped the wrong stock or something? Just my $.02 and $.02 ain't worth much.

Try them out, maybe you will have better luck.
