They are one piece billet black anodised, we stopped selling the welded blue ones as the quality was getting worse and worse.

We did try the asking for bolt length at one point, but again customers weren't happy having to call us twice, once to ask for a diff mount, and again to tell us which bolts, and it was causing issues when people were ordering late in the day and desperate for the parts so we just decided to give them the longest bolts so they will fit every car if the bolts are cut

It's one of those cant do right for doing wrong items. We were getting plenty of moans about them not having Allen headed bolts for clearance, now it seems people want normal bolts, if we supply short bolts people will moan they are shorter than the std ones, long ones some complain they are too long.

The way they are they can fit all scenarios which is the best we can practically achieve
