I picked up my first MRRC car with the Sebring chassis, the Chaparral 2F. Unlike the Sebring chassis used in the Monogram cars, which has bushings front and rear, the front end of the MRRC version has two pairs of 3/32" diameter, but greatly elongated, vertical axle slots, resulting in much too much play in all directions, most notably vertically. I'm pulling the axles and wheels, substituting Slot.it axles, an offset crown gear, bronze bushings in the rear, and BWA 32002/32004 wheels with inserts.
I've been mulling over how to correct the front axle travel. I have several sets of the Slot Car Corner axle posts, which use opposing set screws to set axle height, and was considering trimming the chassis reinforcements and using them, but the chassis is angled (not parallel to the ground) and I'll have to reshape the bottom of the SCC posts to correspond to the vertical slot, and then deepen the SCC posts' vertical slots to match the Sebring chassis slots. The SCC posts might also be glued on the outside of the chassis, but I'd still have to trim them at an angle and they'd have much less chassis-to-post surface area for gluing.
A 1/8" OD x 3/32" ID brass sleeve would work, but drilling two enlarged holes on both sides of the chassis is not easy and I'd have to glue the sleeve on the bottom of the axle locator slot's travel.
If I could just buy a Monogram Sebring chassis, I'd do that!
Any other ideas?
* And has anyone tried to get those very accurate but fragile-looking inserts out of the MRRC wheels to reuse? I think they're photoetched, and they're glued into the plastic wheels - askew, of course. The BWA inserts are accurate for the earlier Chappys, but not for these -- the mesh pattern is different, and the 2F car had knockoffs. *
